                                     PART I

ITEM 1.  DESCRIPTION OF BUSINESS

GENERAL

    PlanetCAD Inc. was incorporated in Delaware on July 7, 1986. We develop,
market and support cycle time reduction software solutions that integrate
engineering processes and data for the manufacturing supply chain. We operate
predominantly in the manufacturing industry with special focus on the
computer-aided design (CAD), manufacturing (CAM) and engineering (CAE) markets.

    In July 2000, we acquired certain assets and liabilities of Prescient
Technologies, Inc. and with it major manufacturing customers in the automotive,
aerospace, electronics and other discrete manufacturing markets worldwide. The
Prescient product line, PrescientQA-TM-, is an integrated suite of engineering
quality tools that allows users, managers and key executives to quantitatively
assess and improve the quality of their product models.

    In November 2000, we sold our component software division to a subsidiary of
Dassault Systemes Corp. in a cash transaction for approximately $25 million,
subject to certain adjustments contemplated by the purchase agreement, and
changed our name from "Spatial Technology Inc." to "PlanetCAD Inc." The sale of
our component software division enabled us to focus our efforts entirely on our
PlanetCAD division, which at the time was primarily an Internet-based services
platform, with the goal of addressing problems that affect data quality and
interoperability in manufacturing. In the first quarter of 2001, however, we
made a strategic decision, for a period of time, to use our Internet-based
services as marketing tools to create name recognition in our market niche and
to promote our enterprise solutions software, rather than to generate revenue
directly from our Internet-based services. Because we had recently sold our
component software division, which had been our most widely recognized division,
we emphasized increasing our presence in our targeted market. This strategy
allowed us to concentrate on developing and selling our enterprise software
solutions.

    In June 2001, we acquired our supply chain management software from Capstone
Ventures SBIC, L.P. and AI Research Corporation for an aggregate purchase price
of $200,000 cash plus warrants to purchase up to 125,000 shares of our common
stock for $1.00 per share. Our supply chain solution performs background
processing and enhances our other products and services that we market and sell
to our customers. It also enables us to bundle, market and sell our software
products and services directly to suppliers and manufacturers, which contract
with original equipment manufacturers, or OEMs, for the outsourced materials and
manufacturing of products developed and designed by others,

                                       1
<Page>
including our existing OEM customers. Including supply chain manufacturers among
our targeted customers significantly increases the potential market for our
suite of software solutions. The software's background processing function
benefits our targeted customers by reducing the manual operation and
manipulation of the CAD, CAM or CAE data during the product translation process
from the end-user's or the OEM's native CAD, CAM or CAE software application
into a format that can be easily and readily used by our customers. The software
also facilitates the rapid communication, tracking and quality checking of that
data to and from authorized parties. The automated process enables our customer
to view and manipulate accurate data received electronically from the end-user
or OEM and simultaneously receive other project information and instructions.
This allows our customer, the supply chain manufacturer, to prepare a more
accurate cost and timeline proposal for the manufacture of the product during
the request-for-quote phase of the manufacturing process. It also helps to avoid
manufacturing errors that can result from the supply chain manufacturer's
inability to view uncorrupted electronic data without using the same software
application used by the end-user or OEM. This cycle time reduction function,
therefore, helps to speed the end-product's time to market. Additionally, supply
chain manufacturers which contract with end-users or OEMs that have not
installed our supply chain management software benefit from the automatic
background processing such as conversion, and translation upon its receipt of
the electronic data in the end-user's or OEM's native computer-aided design,
manufacturing or engineering software application. We have been developing and
enhancing the software since we acquired it, and we launched our first
commercially available version of our supply chain management software,
SCS--Envoy, in late January 2002. While we have yet to close our first sale of
our recently released SCS--Envoy product, we believe that it will develop into
our core product offering over time.

    Our enterprise software products are installed behind a corporate firewall
to help manage transactions and interactive business processes by speeding
engineering data flows between design and manufacturing engineers and their
suppliers. Key features of our enterprise products include:

    - engineering data quality tools that allow engineers, managers and key
      executives to quantitatively assess and improve the quality of their
      product model data;

    - communication of product design data inside a corporate Intranet and
      between the end-users and OEMs and the supply chain manufacturers; and

    - a full featured viewing solution enabling a user to view, mark-up, measure
      and convert file formats without requiring the native applications.

    Our products include software solutions for data interoperability, data
quality management, visualization and collaboration, and process automation. We
focus on providing applications to enhance business practices in the following
areas:

    - improve the accuracy of the design-to-manufacture process;

    - automate time consuming process such as translation, shipping and tracking
      of data;

    - improve new product time to market;

    - lower manufacturing costs; and

    - enable the manufacturing of higher quality products.

    We maintain our corporate headquarters in Boulder, Colorado, from which all
executive, marketing, finance and administrative functions, customer service and
research and development functions are executed. We have one wholly owned
subsidiary, PlanetCAD Limited (United Kingdom), which assists in sales and
licensing of our products internationally.

PRODUCTS AND TECHNOLOGY

    GENERAL

    We provide software tools and applications that enhance the value of
engineering data in the manufacturing design and procurement supply chain by
enabling cycle time reduction. During the traditional manufacturing process, if
the supply chain manufacturer receives a product's specifications and design
electronically, important data may be lost if the supply chain manufacturer does
not use the same software application used by the data originator. In that
event, a sample manufactured product is provided to the end-user or OEM for
approval or modification. If the sample does not meet the end-user's or OEM's
specifications, it must be modified by the supply chain manufacturer and sent
again for approval or modification. This process is often repeated several times
and is costly. "Cycle time" is a term used to describe the cycle of
trial-and-error iterations it takes for the supply chain manufacturer to produce
an end product satisfactory to the end-user or OEM. Our cycle time reduction
solutions enhance engineering processes and reduce product time-to-market by
addressing product data quality, communication and downstream data
interoperability. This includes, but is not limited to, computer-aided design,
data translation and data movement and data tracking that enables communication
of engineering data with varying formats and precision, and data quality
assurance tools that improve design quality and reduce or even eliminate
iterations from electronic design to the finished product meeting the electronic
design standards.

    Our technology and products are based on JAVA, which is a cross-platform,
highly-scalable and internet-enabled development software programming platform.
Our JAVA-based technology and products enable efficient engineering information
exchange and integration for professional manufacturing and design engineers
worldwide. Engineers and managers can benefit from lower costs of production and
accelerated introduction of products to market.

    Our enterprise software products include PrescientQA, IntraVision and our
new SCS--Envoy supply chain solution software. In addition, we offer
professional services that help implement a transparent integration of cycle
time reduction solutions with existing manufacturing systems in corporate
product design and production processes.

    PRESCIENTQA

    Our PrescientQA product line is an integrated suite of engineering quality
tools that provides quality software solutions for manufacturers in the
aerospace, automotive, electronics and other discrete manufacturing industries.
These enterprise-based products detect, assess, correct and prevent product
development problems caused by inaccurate, incomplete or inconsistent design
modeling practices. The core components of the PrescientQA suite include:

information and engineering data from the end-user or OEM to their supply chain.
This automatic processing, packaging and communication enables the supply chain
manufacturer to view, quality check and manipulate accurate data received
electronically from the end-user or OEM. Additionally, manufacturers with access
to our supply chain solution can send, receive and collaborate with anyone in
the supply chain instantly, with accurate real-time information, anywhere in the
world. We first released our SCS--Envoy product in late January, and as of March
27, 2002, had not made any sales.

DEVELOPMENT CONSULTING SERVICES

    We also provide consulting services to our customers to help them
understand, integrate and use our products in their current supply chain
processes. We can customize our products to address their

                                       4
<Page>
unique requirements and business needs. We believe that providing our customers
with this high level of service will help retain and attract new business and
differentiate us from our competitors.

CUSTOMERS

    Our existing customers are typically from the automotive, aerospace,
electronics and other discrete manufacturing markets worldwide and they use our
cycle time reduction solutions to access, exchange and share product data
throughout their engineering and manufacturing processes to reduce their costs
of innovation and product development. Many customers are Fortune 1000
manufacturers that manage the production process through a wide network of
suppliers needing access to engineering data rapidly and without manual
intervention. Our current customers, which are also targeted customers with
respect to our recently released SCS--Envoy product, include Lockheed Martin,
Black & Decker, Freightliner Trucks and Boeing Helicopter. While one customer
accounted for 13% of our sales for 2000, we are not dependent on any one major
customer and no customer accounted for more than 10% of our sales during 2001.

    With the introduction in late January 2002 of SCS--Envoy, our supply chain
management software, we are targeting middle market supply chain manufacturers
which service our existing customers and other OEMs and which have annual
revenues of approximately $200 million to $800 million. By providing the supply
chain manufacturers with accurate access to product design data, they may
interface directly with an OEM's procurement, design and engineering divisions
to access, exchange and share product data accurately and efficiently, reducing
manufacturing iterations, improving the end-product's time to market and
reducing overall manufacturing costs.

RESEARCH AND PRODUCT DEVELOPMENT

    We believe that our continued growth will depend in large part on our
ability to maintain and enhance our current products, develop new products and
maintain technological competitiveness. We have built a development group with
specialized industry-specific development techniques in advanced mathematics and
C++ programming. During 2001 and 2000, our research and development expenses
were $4.4 million and $6.3 million, respectively. Because of our working capital
restraints, however, we expect our 2002 research and development expenditures to
be significantly reduced.

    We augment our internal development capabilities through a network of
development partners who have complementary programming expertise. Depending on
the product involved, we may own, co-own or license the technology we market and
distribute. For many products, we have exclusive rights to market and distribute
the technology. We utilize development partners to reduce our research and
development expenses and to obtain the expertise of skilled programmers who are
not our employees.

SALES, MARKETING AND DISTRIBUTION

    We sell our software products through our direct and indirect worldwide
sales organization. We maintain two offices for our direct sales force: one is
located in Boulder, Colorado and the other is located in the United Kingdom.
Application specialists provide support to prospective customers on product
information and deployment options to compliment our direct sales force. Our
pre-sales support is comprised of four employees.

    We primarily target our marketing efforts at senior executive and
engineering management. In connection with SCS--Envoy, our supply chain
management software product, we are primarily targeting our marketing efforts at
senior executive management and engineering, procurement and manufacturing
executives. Our marketing efforts are designed to generate new sales
opportunities for our various products and create brand awareness. We engaged in
numerous marketing activities in 2001, including online and offline advertising,
direct e-mail campaigns, participation in trade shows and

                                       5
<Page>
public relations. Because of our working capital restraints, however, we expect
our 2002 marketing expenditures to be significantly reduced.

CUSTOMER SERVICE AND SUPPORT

    We believe that customer service and support is critical to the success of
our products. Customer phone calls or e-mails are answered and managed by our
support professionals who review customer communications with the appropriate
development group and coordinate the response to the customer. Our response time
varies depending upon the complexity of the question or issue at hand, but we
generally respond within 24 hours.

    As part of our licensing arrangements for all products, we offer maintenance
services that include technical updates and product support. To date, a majority
of our customers have purchased these maintenance services, which we offer on a
renewable basis for an annual fee. These services allow our customers full
access to the products they have licensed, including all new releases, telephone
support and other support required to effectively utilize our products.

COMPETITION


    The markets for our products are highly competitive, subject to rapid change
and characterized by constant demand for new product features and pressure to
accelerate the release of new products and product enhancements and to reduce
prices. The principal methods of competition in the markets in which we compete
include: product functionality and quality; product-related services such as
customer support and implementation services; price; compliance with industry
standards and requirements; the ability of the solution to generate business
benefits; rapid return on investment; and financial stability. We face
competition on several fronts, including both larger mechanical engineering
software and supply chain management software companies and smaller start-ups.
Depending on the product, our competitors include INCAT Systems, Inc.,
Parametric Technology Corporation, TransCAT GmbH, International TechneGroup
Incorporated, Proficiency, Inc. and Manugistics Inc. A number of other large
companies compete with us indirectly because they provide similar products to
our customers, or potential customers, bundled with the purchase of other
products. Because most of our competitors or potential competitors have
significantly greater financial, managerial, technical and marketing resources
than we do, our competitive position is relatively disadvantaged.


INTELLECTUAL PROPERTY

    We regard our technology as proprietary and we rely heavily on a combination
of copyright, trademark and trade secret laws, employee and third party
nondisclosure agreements, and other intellectual property protection methods to
protect our products and technology. Currently, we do not have any patents with
respect to our technology. Existing copyright laws afford only limited
protection, and it may be possible for unauthorized third parties to copy our
products or to reverse engineer or obtain and use information that we regard as
proprietary. Because we license portions of our technology and also resell
certain component extensions of third party software developers to unrelated
third parties, it is difficult to monitor what those third parties do with the
licensed or sold property.

    While we are not aware that any of our products infringe upon the
proprietary rights of any third parties, it is possible that third parties may
claim infringement by us with respect to current or future products. We expect
that we could increasingly be subject to such claims as the number of products
and competitors in the supply chain management, enterprise solutions and product
data software markets grow and the functionality of such products overlap with
other industry segments.

EMPLOYEES

    As of December 31, 2001, we had 31 full-time employees, 19 of whom were
engaged in product development, quality assurance and technical support, 7 of
whom were engaged in sales and marketing and 5 of whom were engaged in
administration. Our employees are not subject to any collective bargaining
agreements, and we believe our relations with our employees are good.

FACTORS AFFECTING OUR BUSINESS, OPERATING RESULTS, FINANCIAL CONDITION AND
  COMMON STOCK

    THE FOLLOWING RISK FACTORS SHOULD BE CONSIDERED CAREFULLY IN EVALUATING
PLANETCAD AND OUR BUSINESS BECAUSE SUCH FACTORS CURRENTLY HAVE A SIGNIFICANT
IMPACT, OR MAY HAVE A SIGNIFICANT IMPACT, ON THE FUTURE OF OUR BUSINESS,
OPERATING RESULTS OR FINANCIAL CONDITION, AND THE MARKET FOR OUR COMMON STOCK.

    WE HAVE A HISTORY OF LOSSES AND EXPECT LOSSES TO CONTINUE FOR THE
FORESEEABLE FUTURE

    As of December 31, 2001 and 2000, we recorded an accumulated deficit of
$30.1 million and $18.8 million, respectively. On a stand-alone basis, our
PlanetCAD division experienced operating losses in each quarterly period since
its inception. We expect to continue to incur net losses for the foreseeable
future because our expected operating and marketing expenses will increase as we
attempt to grow our business. With increased expenses, we will need to generate
significant additional revenue to achieve profitability. As a result, we may
never become profitable. Even if we do achieve profitability in any period, we
may not be able to sustain or increase profitability on a quarterly or an annual
basis.

    WE ARE IMPLEMENTING A NEW AND UNPROVEN BUSINESS MODEL

    Our business model is new and unproven and may never be successful. The
success of the business plan depends on a number of factors. These factors
include:

    - competition from other supply chain management software developers, most
      of whom are significantly larger or have significantly greater financial
      and marketing resources than we do;

    - our ability to introduce and sell our products, specifically SCS--Envoy,
      to supply chain manufacturers of our existing customers;

    - our ability to differentiate our product offerings, specifically
      SCS--Envoy, from those of our competitors;

    - acceptance by customers of supply chain management functionality with
      engineering integration as a differentiator; and

    - our ability to implement new and additional services useful to the
      engineering software and supply chain manufacturing markets.

    We will need to develop new products and enhance existing products, services
and software that stimulate and satisfy customer demand. If we fail to achieve
these objectives, our business may not be viable. End-users and mid-market
supply chain manufacturers may fail to adopt our supply chain management
products and application services for a number of reasons, including:

    - lack of information technology budget to allocate for the purchase of our
      enterprise software solutions and services;

    - lack of confidence in our long-term strength as a service provider;

    - lack of knowledge and understanding of the return on investment and
      benefits provided with supply chain management applications with
      integrated engineering data exchange;

    - the look and feel of supply chain management products, quality and other
      manufacturing industry-related applications and services; and

                                       7
<Page>
    - actual or perceived limitations in selection and availability of supply
      chain management products, quality and other manufacturing
      industry-related applications and services.

    WE MAY BE UNABLE TO RAISE ADDITIONAL CAPITAL ON FAVORABLE TERMS OR AT ALL

    We may need to raise additional capital to fund operating losses, develop
and enhance our services and products, fund expansion, respond to competitive
pressures or acquire complementary products, businesses or technologies. We may
not be able to raise additional financing on favorable terms, if at all. If we
raise additional funds through the issuance of equity or convertible debt
securities, the percentage ownership of our stockholders will be reduced and the
securities issued may have rights, preferences or privileges senior to those of
our common stock. If we cannot raise adequate funds on acceptable terms, our
ability to fund growth, take advantage of business opportunities, develop or
enhance services or products or otherwise respond to competitive pressures will
be significantly limited. In that event, our business could be harmed, our
operating results and financial condition could be adversely affected and the
market price for our common stock could decline.

    WE ARE HIGHLY DEPENDENT ON THE SUCCESS OF OUR SUPPLY CHAIN MANAGEMENT
SOFTWARE

    The market for SCS--Envoy, our supply chain management software, and our
related services is at an early stage of development. Our success depends on a
significant number of buying organizations and marketplaces implementing our
products and services. The implementation of our products by these organizations
is often perceived as complex, time consuming and expensive. In many cases,
these organizations must change established business practices and conduct
business in new ways. Our ability to attract additional customers for our
products and services will depend in large part on our ability to use our
existing customers as reference accounts. Unless a critical mass of buying
organizations, their suppliers and marketplaces adopt our supply chain
management solutions, our products and services may not achieve widespread
market acceptance and our business could be materially adversely affected. We
began marketing SCS--Envoy in late January 2002 and, as of March 27, 2002, have
not made any sales.

    WE HAVE A LIMITED OPERATING HISTORY

    Although our company has been operating since July 1986, our PlanetCAD
division was not introduced until June 1999 and our first PlanetCAD application
service was not launched until November 1999. In November of the following year,
we sold our component software division, the division around which we were
founded, to a wholly owned subsidiary of Dassault Systemes Corp. Since that
time, with the acquisition in June 2001 of our supply chain management
application services capabilities, we have changed the focus of our PlanetCAD
operations from providing Web-based applications services to providing cycle
time reduction services and solutions for the manufacturing supply chain. The
limited history and continuing evolution of our PlanetCAD operations makes it
difficult to evaluate our business and prospects. Our prospects must be
considered in light of the risks, uncertainties, expenses and difficulties
frequently encountered by companies in their early stages of development,
particularly companies with limited resources attempting to use technology to
change long-established businesses and consumer behavior. These risks and
uncertainties are discussed throughout this section. If we fail to address these
risks and uncertainties, we may be unable to grow our business, increase our
revenue or become profitable.

    COMPETITION IN OUR INDUSTRY IS INTENSE

    The markets for our products and services are highly competitive, rapidly
changing and subject to constant technological innovation. Participants in these
markets face constant pressure to accelerate the release of new products,
enhance existing products, introduce new product features and reduce prices.
Most of our competitors or potential competitors have significantly greater
financial, managerial,

                                       8
<Page>
technical and marketing resources than we do. Actions by competitors that could
materially adversely affect our business, financial condition and results of
operations include:

    - a reduction in prices for their products or services;

    - increased promotional and marketing expenses

    - accelerated introduction of, or the announcement of, new or enhanced
      products, services or features;

    - acquisitions of competitive software applications or technologies from
      third parties; or

    - product or service giveaways or bundling.

    In addition, our present and future competitors may be able to develop
comparable or superior products or respond more quickly to new technologies or
evolving standards. Accordingly, we may be unable to consistently compete
effectively in our markets, competition might intensify or future competition
may develop, all of which could materially adversely affect our business,
financial condition, results of operations or market for our common stock.

    WE MAY FAIL TO MEET EXPECTATIONS BECAUSE OF THE IMPACT OF CHANGING GLOBAL
ECONOMIC CONDITIONS ON OUR CUSTOMERS

    Our operating results can vary significantly based upon the impact of
changes in global economic conditions on our customers. More specifically, the
macro-economic environment of 2001 proved more uncertain than in recent prior
periods. The revenue growth and profitability of our business depends on the
overall demand for supply chain management software and services, particularly
in the markets in which we compete. Because our sales are primarily to corporate
customers whose businesses fluctuate with general economic and business
conditions, a softening of demand for computer software caused by a weakening
economy may result in decreased revenue and lower growth rates. Customers may
defer or reconsider purchasing our products if they experience a downturn in
their business or if there is a downturn in the general economy.

    OUR REVENUE MAY FLUCTUATE BECAUSE OF UNPREDICTABLE ECONOMIC CYCLES AND
UNCERTAIN DEMAND FOR OUR SUPPLY CHAIN MANAGEMENT CAPABILITIES

    Demand for our supply chain management and other services is affected by the
general level of economic activity in the markets in which we operate, both in
the United States and abroad. Our customers and the markets in which we compete
to provide our products and services are likely to experience periods of
economic decline from time to time. Adverse economic conditions may decrease our
customers' willingness to make capital expenditures or otherwise reduce their
spending to purchase our products and services, which could result in diminished
revenue and margins for our business. In addition, adverse economic conditions
could alter the overall mix of services that our customers seek to purchase, and
increased competition during a period of economic decline could force us to
accept contract terms that are less favorable to us than we might be able to
negotiate under other circumstances. Changes in our product offering mix or a
less favorable contracting environment may cause our revenue and margins to
decline.

    OUR PRODUCTS MAY CONTAIN UNDETECTED ERRORS

    Our business depends on complex computer software, both internally developed
and licensed from third parties. Complex software often contains defects,
particularly when first introduced or when new versions are released. Although
we conduct extensive testing, we may not discover software defects that affect
our new or current products and services or enhancements until after they are
deployed. In the past, we have discovered software errors in some new products
and enhancements after their

                                       9
<Page>
introduction. We may find errors in current or future new products or releases
after commencement of commercial use. If we market products and services that
contain errors or that do not function properly, we may experience negative
publicity, loss of or delay in market acceptance, or claims against us by
customers, any of which could harm our current and future sales, or result in
expenses and liabilities that could reduce our operating results and adversely
affect our financial condition and market for our common stock.

    WE DEPEND ON SWIFT AND TIMELY INTRODUCTIONS OF NEW PRODUCTS

    We compete in an industry continuously faced with evolving standards and
rapid technological developments. New products are introduced frequently and
customer requirements change with technology developments. Our success will
depend upon our ability to anticipate evolving standards, technological
developments and customer requirements and accordingly to enhance our existing
products. We have experienced delays in the development of certain new products
and product versions. Additionally, we use third party development partners to
facilitate the development of product enhancements and extensions. Delays in
product development may adversely affect our business, financial condition and
operating results. Negative reviews of new products or product versions could
also materially adversely affect market acceptance.

    WE ARE DEPENDENT UPON KEY PERSONNEL AND THE ABILITY TO HIRE ADDITIONAL
     PERSONNEL

    Our executive officers and key employees are vital assets. We depend on the
ability to attract, retain and motivate high quality personnel, especially
management, skilled development personnel and sales personnel. Competition for
skilled development personnel with specialized experience and training relevant
to supply chain management software is intense. There are a limited number of
experienced people in the United States with the skills and training we require.
The loss of any of our key employees could materially adversely affect our
business, financial condition or operating results. Our failure to recruit
executive officers or key sales, management or development personnel would
similarly harm our growth and competitiveness.

    WE MAY NOT BE ABLE TO EFFECTIVELY EXPAND OUR OPERATIONS

    Our future success will depend, in part, upon our ability to:

    - introduce competitive products on a timely basis;

    - continue to enhance our suite of products;

    - respond to competitive developments;

    - expand our sales and marketing efforts; and

    - attract, train, motivate and retain qualified management, software
      development and engineering personnel.

    Although we believe our systems and controls are adequate for our current
level of operations, we may need to add personnel and expand and upgrade our
systems and controls to meet these challenges. Failure to do so could have a
material adverse effect upon our business, financial condition and results of
operations.

    WE MAY NOT BE ABLE TO EFFECTIVELY INTEGRATE RECENT ACQUISITIONS OR FUTURE
     STRATEGIC ACQUISITIONS

    In June 2001 we completed the acquisition of our supply chain management
software solutions. In the future, we may find it necessary or desirable to
acquire additional complementary businesses, products or technologies. If we
identify an appropriate acquisition candidate, we may not be able to negotiate
the terms of the acquisition successfully, finance the acquisition, or integrate
the acquired

                                       10
<Page>
business, products or technologies into our existing business and operations. If
our efforts are not successful, our business could be materially adversely
affected.

    Completing any future acquisitions, and integrating our recent product
acquisition could cause significant diversions of management time and resources.
Managing acquired businesses entails numerous operational and financial risks.
These risks include difficulty in assimilating acquired operations, diversion of
management's attention and the potential loss of key employees or customers of
acquired operations. We may not be able to effectively integrate any such
acquisitions, and our failure to do so could result in lost revenue or
materially reduce our operating results.

    Furthermore, if we consummate one or more significant future acquisitions in
which the consideration consists of our stock or other securities, our equity
could be significantly diluted. If we consummate any significant future
acquisitions in which the consideration consists of cash, a substantial portion
of our cash available for operations could be depleted. Financing for future
acquisitions may not be available on favorable terms, or at all.

    WE MAY BE EXPOSED TO RISKS OF INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS
     INFRINGEMENT

    Our proprietary technologies are critical to our success and ability to
compete. We rely on trade secret and copyright laws to protect our proprietary
technologies, but our efforts may be inadequate to protect these proprietary
rights or to prevent others from claiming violations of their proprietary
rights. We have no patents with respect to the technology we use. Further,
effective trade secret and copyright protection may not be available in all
foreign countries.

    We generally enter into confidentiality or license agreements with employees
and consultants. Additionally, we seek to control access to and distribution of
our proprietary software, documentation and other information. Despite our
efforts to protect our proprietary rights, unauthorized parties may attempt to
copy aspects of our products or to obtain and use information that we regard as
proprietary. Monitoring and restricting unauthorized use of our proprietary
information is difficult.

    The unauthorized misappropriation of our technology could have a material
adverse effect on our business, financial condition, results of operations and
market for our common stock. If we resort to legal proceedings to enforce our
proprietary rights, the proceedings could be burdensome and expensive and could
involve a high degree of risk.

    We may also be subject to claims alleging that we have infringed third party
proprietary rights. Litigating such claims, whether meritorious or not, is
costly and could materially adversely affect our results of operations. These
claims might require us to enter into royalty or license agreements with terms
unfavorable to us. If we were found to have infringed upon the proprietary
rights of third parties, we could be required to pay damages, cease sales of the
infringing products or redesign or discontinue such products, any of which could
materially reduce our sales and results of operations and cause a decline in the
market price for our common stock.

    OUR RESTATED CERTIFICATE OF INCORPORATION, AS AMENDED, BYLAWS AND
ANTI-TAKEOVER PROTECTIONS COULD DELAY OR PREVENT AN ACQUISITION OR SALE OF
PLANETCAD

    Certain provisions of our restated certificate of incorporation, as amended,
and bylaws, as well as certain provisions of the General Corporation Law of the
State of Delaware, may deter, discourage or make more difficult a change in
control, even if such a change in control would benefit our stockholders. In
particular:

    - our certificate of incorporation authorizes the board of directors to
      issue one or more classes of preferred stock having such designations,
      rights and preferences as they determine, which issuances may have a
      material adverse effect on the rights of holders of common stock;

                                       11
<Page>
    - our stockholders have no right to take action by written consent;

    - only stockholders owning not less than two-thirds of the outstanding
      shares may call special meetings of stockholders;

    - our bylaws contain advance notice provisions for presentation of new
      business and nominations of directors at meetings of stockholders; and

    - our bylaws may be amended only by the board of directors or by the
      affirmative vote of sixty-six and two-thirds percent of the voting power
      of all of the then-outstanding shares of our voting stock.

    In addition, under the terms of our recently adopted stockholder rights
plan, in general, if a person or group acquires more than 15% of the outstanding
shares of our common stock, all of our other stockholders would have the right
to purchase securities from us at a discount to such securities' fair market
value, thus causing substantial dilution to the holdings of that acquiring
person or group. The stockholder rights plan may inhibit a change in control
and, therefore, could materially adversely affect our stockholders' ability to
realize a premium over the then-prevailing market price for our common stock in
connection with such a transaction.

    Delaware law may also discourage, delay or prevent someone from acquiring or
merging with us. Under Delaware law, a corporation may not engage in a business
combination with any holder of 15% or more of its capital stock until the holder
has held the stock for three years unless, among other possibilities, the board
of directors approves the transaction. Our board of directors could use this
provision to prevent or delay takeovers.

    These provisions could discourage potential acquisition proposals and could
delay or prevent a change of control transaction. As a result, they may limit
the price investors may be willing to pay for our stock in the future.

    OUR STOCK PRICE IS HIGHLY VOLATILE

    The market price of our common stock has been highly volatile and is likely
to continue to be volatile. Factors affecting our stock price may include:

    - fluctuations in our sales or operating results;

    - announcements of technological innovations or new software standards by us
      or competitors;

    - published reports of securities analysts;

    - developments in patent or other proprietary rights; o changes in our
      relationships with development partners; and

    - general market conditions, especially regarding the general performance of
      comparable technology stocks.

    Many of these factors are beyond our control. These factors may materially
adversely affect the market price of our common stock, regardless of our
operating performance.

    IMPACT OF PCD INVESTMENTS, LLC'S ACTIONS ON OUR CUSTOMER AND EMPLOYEE
     RELATIONS

    Beginning in December 2001, PCD Investments, LLC, which has acquired
approximately 15% of our outstanding common stock since October 2001 and is our
largest stockholder, has made various proposals to purchase our outstanding
shares of common stock, including a potential hostile tender offer. PCD
Investments subsequently announced that it did not plan to commence the tender
offer, but that it intended to nominate at the 2002 annual meeting six
individuals to serve as members of our board of directors. The uncertainty
arising from PCD Investments' actions and threatened actions has

                                       12
<Page>
disrupted our operations, diverted management's attention and affected our
relationships with our customers and employees. The continuing uncertainty may
have a material adverse effect on our business, financial results and customer
and employee relations, and may adversely affect the market for our common
stock.

    WE FACE DIFFICULTIES DOING BUSINESS IN INTERNATIONAL MARKETS

    Our ability to sell our products and services in international markets will
depend in part on risks inherent in doing business on an international level.
Factors that may affect our international expansion efforts include:

    - our inability to obtain or resolve uncertainties concerning territorial
      rights to software;

    - copyright laws that are not uniform, or uniformly enforced, in all
      countries;

    - export restrictions;

    - export controls relating to encryption technology;

    - longer payment cycles;

    - problems in collecting accounts receivable;

    - political and economic instability; and

    - potentially adverse tax consequences.

    We have no control over many of these factors and the occurrence of any of
them could harm our international business efforts.

ITEM 2.  DESCRIPTION OF PROPERTY

    Our principal executive office is located at 2520 55th Street, Suite 200,
Boulder, Colorado 80301, where we lease approximately 15,600 square feet of
office space. Monthly base lease payments for this facility are approximately
$33,100 and the lease for this facility expires September 1, 2007. Management
believes that our leased property is suitable and adequate for its intended use
and that the property is adequately covered by insurance.

ITEM 3.  LEGAL PROCEEDINGS

    From time to time we have been involved in litigation relating to claims
arising out of our operations in the normal course of business. As of the date
of this filing, we are not a party to, nor are any of our properties subject to,
any legal proceedings other than routine litigation incidental to our business.

OVERVIEW


    Except for the historical information contained herein, the following
discussion contains forward-looking statements that involve risks and
uncertainties. Our actual results could differ materially from those discussed
here. Factors that could cause or contribute to such differences include, but
are not limited to, those discussed under the caption "Factors Affecting Our
Business, Operating Results, Financial Condition and Common Stock" in Part I of
this Annual Report on Form 10-KSB.


    Historically, our core business has been to provide three-dimensional
modeling software to the computer aided design, manufacturing and architecture
industries. In 1999, we supplemented our core business when we launched our
PlanetCAD division operations, which has evolved since its initial launch and
now provides interoperability and cycle time reduction solutions and services
for the manufacturing supply chain. Key milestones for our transition to
focusing exclusively on our PlanetCAD operations include:

    - ACQUISITION OF PRESCIENT TECHNOLOGY, INC. In July 2000, we acquired
      certain assets and liabilities of Prescient Technologies, Inc. and with it
      major manufacturing customers in the automotive, aerospace, electronics
      and other discrete manufacturing markets worldwide. Prescient's product
      line, PrescientQA-TM-, is an integrated suite of engineering quality tools
      that allow users, managers and key executives to quantitatively assess and
      improve the quality of their product models.

    - SALE OF COMPONENT SOFTWARE DIVISION. In November 2000, we sold our
      component software division to a subsidiary of Dassault Systemes Corp. and
      changed our name to "PlanetCAD Inc." The sale of our component software
      division enabled us to focus our efforts entirely on our PlanetCAD
      operations, which at the time was primarily an Internet-based services
      platform, with the goal of addressing problems that affect data quality
      and interoperability in manufacturing. In the first quarter of 2001,
      however, we made a strategic decision, for a period of time, to use our
      Internet-based services as marketing tools to create name recognition in
      our market niche and to promote our enterprise solutions software, rather
      than to generate revenue directly from our Internet-based services.
      Because we had recently sold our component software division, which had
      been our most widely recognized division, we emphasized increasing our
      presence in our targeted market. This strategy allowed us to concentrate
      on developing and selling our enterprise software solutions, which are
      software products that are installed within a corporate firewall to help
      manage transactions and interactive business processes by speeding
      engineering data flows between design and manufacturing engineers and
      their suppliers.

    - ACQUISITION OF SUPPLY CHAIN SOFTWARE. In June 2001, we acquired our supply
      chain management software from Capstone Ventures SBIC, L.P. and AI
      Research Corporation. The software integrates or interfaces with our
      existing software solutions to perform background processing and enhances
      our other products and services that we market and sell to our customers.
      It also enables us to bundle, market and sell our software products and
      services directly to supply chain manufacturers, which contract with
      end-users and original equipment manufacturers, or OEMs, for the
      outsourced manufacturing of products developed and designed by others,
      including our existing OEM customers. Including supply chain manufacturers
      among our targeted customers significantly increases the potential market
      for our suite of software solutions.

    - RELEASE OF SCS--ENVOY. On January 22, 2002, we launched our first
      commercially available version of our supply chain management software,
      SCS--Envoy, which is an enterprise interoperability solution that
      streamlines the handling, security and transmission of all manufacturing
      data so that it can be distributed rapidly throughout the supply chain.
      SCS--Envoy is specifically created to handle all enterprise data
      distribution processes, including engineering and product data, database
      information, financial and procurement information to multiple authorized
      recipients while reducing the "down time" of lengthy manual processes. We
      believe our solution addresses the remaining areas in manufacturing that
      cause manufacturing delays,

                                       16
<Page>
      reducing costs and decreasing time-to-market, and addresses the critical
      need to get the right data out to the right people in a format that can be
      used immediately. As of March 27, 2002, we have not made any sales of our
      SCS--Envoy product.

    We have two sources of revenue: license fees and service fees, the latter of
which includes fees for our maintenance, training and consulting services.
License fees consist of fees paid by customers to license our products for use
in our customers' product development efforts. Revenue from license fees is
recognized upon completion of a signed contract and shipment of product assuming
all other criteria for revenue recognition are met. Revenue from service fees is
recognized as follows: maintenance fee revenue, consisting of fees received by
us for customer support and product upgrades, is generally based on annual
contracts and is recognized ratably over the period of the contract; and
training and consulting fee revenue is recognized upon completion of a training
class or the performance of services, respectively.

    For the year ended December 31, 2001, we had a net loss of $11.4 million (or
$0.91 per share) on total revenue of $1.8 million, as compared to net income of
$1.2 million (or $0.10 per share) on total revenue of $2.1 million reported for
2000. The net loss for 2001 includes a $1 million gain on the sale of our
component software division and the net income for 2000 includes a $4.8 million
loss from discontinued operations and a $17.4 million gain on the sale of our
component software division.

    As of December 31, 2001, we had net operating loss carryforwards totaling
approximately $24.6 million, which may be used to reduce future income taxes.
Utilization of these net operating loss carryforwards may be limited under
certain circumstances. See Note 6 to our Consolidated Financial Statements
included under Item 7 of this Annual Report on Form 10-KSB.

FISCAL YEARS ENDED DECEMBER 31, 2001 AND 2000

REVENUE.

    Our revenue consists of software license revenue and service revenue.
Software license revenue consists of sales of software licenses, which are
recognized in accordance with the American Institute of Certified Public
Accountants' Statement of Position SOP 97-2, Software Revenue Recognition, as
modified by SOP 98-9 ("SOP 97-2"). Under SOP 97-2, software license revenue is
recognized upon execution of a contract and delivery of software, provided that
the license fee is fixed and determinable, no significant production,
modification or customization of the software is required and collection is
considered probable. In addition, SOP 97-2 requires that revenue recognized from
software arrangements be allocated to each element of a multiple element
arrangement based on vendor specific objective evidence of fair value for each
element. Service revenue is primarily derived from customer maintenance
agreements generally entered into in connection with the initial license sale
and subsequent renewals, and fees for implementation of, consulting on and
training services for our software products. Maintenance revenue is recognized
ratably over the term of the maintenance period and service revenue is
recognized as the services are performed. Payments for maintenance fees are
generally collected in advance of performance.


    Total revenue decreased 14.2% to $1.8 million for 2001 as compared to $2.1
million for 2000. License fees decreased 65.5% to $552,000 for 2001, as compared
to $1.5 million for 2000. The decrease in software license revenues in 2001 was
partly the result of a decline in sales arising from the weakening macroeconomic
environment and a decline in demand for our products and services, which was
partly due to increased competition. All of the decline occured in the Prescient
product line. Poor economic conditions caused a significant decrease in
technology and capital spending and extended the decision cycles of many
potential customers. We were particularly affected because we have historically
derived a large percentage of our revenue from the aerospace and automotive
industries, which appear to have been more significantly adversely impacted by
the poor economic conditions. The terrorist attacks on September 11, 2001
further compounded the recession-like environment, causing customers to postpone
or cancel projects and disrupting sales cycles. In addition, our release of
updated products in June 2001 was the first release of an updated product
offering in eighteen months. During this period, companies developing
computer-aided-design software expanded their product lines to include software
with some features similar to our Prescient products. This increased competition
further contributed to the decline of our license revenue. Service revenue
increased 117.9% to $1.3 million for 2001, as compared to $587,000 for 2000,
reflecting a full year of service revenue in 2001, compared to six months of
revenue in 2000.


COST OF REVENUE.

    Cost of license fees consists primarily of royalty fees associated with
third-party software included with our software and the cost of reproduction and
delivery of the software. Cost of license fees was $512,000 and $818,000 for the
years December 31, 2001 and 2000, respectively, representing 98% and 54% of
license revenue, respectively. The increase in cost of license revenue was
primarily attributable to an increase in royalty fees associated with third
party software. Certain agreements have minimum royalty fees, which can exceed
the revenue related to product sales.

    Cost of services consists primarily of costs associated with providing
software maintenance to customers such as telephone support and packaging and
shipping costs related to new releases, as well as costs associated with our
implementation, consulting and training services. Cost of services was $959,000
and $220,000 for the years ended December 31, 2001 and 2000, respectively,
representing 75% and 37% of services revenue, respectively. The increase in cost
of services as a percentage of services revenue in dollar amount is attributable
to the hiring and training of additional consultants, and increased product
support, and reflects a full year of service costs in 2001, compared to six
months of service costs in 2000.

                                       18
<Page>
OPERATING EXPENSES.

    Total operating expenses increased 0.3% to $12.8 million for 2001 from $12.4
million for 2000. The increase in total operating expenses reflects a full year
of expenses for the Prescient product line in 2001, compared to six months of
expenses in 2000. The increase in operating expenses was also due to increased
staffing to support the development of our supply chain management software. As
a percent of total revenue, total operating expenses increased to 709% for 2001
as compared to 592% for 2000.

SALES AND MARKETING EXPENSES.

    Sales and marketing expenses consist primarily of personnel costs,
commissions, travel, office facilities, promotional events such as trade shows,
seminars and technical conferences, advertising and public relations programs.
Sales and marketing expense was $3.1 million for both 2001 and 2000. Although
sales and marketing expenses for 2001 reflect a full year of costs for the PQA
product line, compared to six months of costs in 2000, total expenses remained
flat due to savings from closing field offices, headcount reductions and lower
commission expenses due to decreased revenue. Sales and marketing expense for
2001 increased as a percent of total revenue to 173% versus 148% for 2000. The
increase in sales and marketing expenses as a percentage of total revenue is
primarily a result of decreased revenue.

RESEARCH AND DEVELOPMENT EXPENSES.


    Research and development expenses consist primarily of personnel costs,
third party consultant costs, and depreciation of development related assets.
Research and development expense decreased 30% to $4.4 million for 2001 from
$6.3 million for 2000. Decreased research and development expense resulted from
staffing reductions relating to the termination of development of our 3DShare
product line, as well as general headcount reductions and cost controls.
Research and development expenses for both 2001 and 2000 also included
approximately $700,000 for outside consulting services related to development of
the PQA product line. As a percent of total revenue, research and development
expense decreased to 244% for 2001 from 300% for 2000. The decrease in research
and development expenses as a percentage of total revenue is also attributable
to decreased headcount and general cost controls.


GENERAL AND ADMINISTRATIVE EXPENSES.


    General and administrative expenses include the personnel and other costs of
our finance, accounting, human resources, information systems and executive
departments, as well as corporate facilities expenses. General and
administrative expenses increased 57% to $4.2 million for 2001 from $2.7 million
for 2000. As a percent of total revenue, general and administrative expense
increased to 235% for 2001 from 128% for 2000. The increase in general and
administrative expenses in dollar amount and as a percentage of total revenue is
primarily attributable to increased staffing, $845,000 in office space expenses,
severance payments made in connection with our reduction in force, legal and
accounting fees of $475,000 and $275,000 in other infrastructure expenses
incurred in support of our PlanetCAD operations as a stand-alone public
corporation. General and administrative expenses for 2000 reflect only those
costs associated with the PlanetCAD division of our company, which at the time
also had a separate component software division.


IN-PROCESS RESEARCH AND DEVELOPMENT.

    In-process research and development expense of $332,000 for 2000 relates to
the acquisition of certain assets and liabilities of Prescient. There was no
acquired in-process research and development expense for 2001.


RESTRUCTURING CHARGES.



    During the third quarter of 2001, the Company initiated a restructuring plan
to reduce our operating expenses and strengthen both our competitive and
financial positions by eliminating


                                       19
<Page>

employee positions and reducing office space and related overhead expenses. In
addition to terminating our 3DShare product line, the cost reductions impacted
all departments. Overall expense reductions were necessary both to lower
existing cost structure and to reallocate resources to pursue future operating
strategies in response to declining revenue and other performance measures
during 2001. Restructuring charges primarily consisted of $623,000 for severance
and termination costs associated with the reduction in force of 21 employees,
all of which was paid in 2001. In connection with the restructuring, the Company
accrued an additional $400,000 in lease abandonment costs, $245,000 of which was
paid during 2001. The remaining $155,000 represents the lease costs due over the
next four years not offset by sublease income. Each quarter the Company expects
to save $725,000 in salary and benefits expense, $75,000 in facility related
expenses and $150,000 in consulting costs. These expense reductions will be
reflected in service costs of sales and sales and marketing, research and
development and general and administrative expenses. Total operating costs
decreased $1.1 million in the fourth quarter of 2001 when compared to the total
operating costs before restructuring costs in the third quarter of 2001.
Additional details of the restructuring charges are presented in Note 10--
Restructuring Costs in the Notes to Consolidated Financial Statements included
in Item 7 of this report.


DISCONTINUED OPERATIONS, COMPONENT SOFTWARE DIVISION.

    Net loss from discontinued operations was $4.8 million for 2000. The net
loss in 2000 was primarily due to decreased revenue due in part to increased
resistance to up-front license fees by software developers in an increasingly
competitive market, as well as from changes to the pricing model for our
component software division products. Under a new pricing model, component
licensees paid only recurring fixed and variable partner fees upon the release
and shipment of a software application that incorporated our component software.

LIQUIDITY AND CAPITAL RESOURCES

    As of December 31, 2001, we had $5.4 million in cash and cash equivalents.
Cash and cash equivalents decreased $12.9 million for the year ended December
31, 2001, as compared to an increase of $17.0 million for the prior year. This
decrease is primarily due to a net operating loss of $11.4 million, a $3.4
million decrease in accounts payable and accrued liabilities, partially offset
by the $1.0 million gain on the disposal of our component software division. The
increase in cash in 2000 was primarily due to the sale of the component software
division, the sale of 555,556 shares of our common stock to Dassault, and the
sale of shares of our common stock to investors in a February 2000 private
equity transaction. The 555,556 shares were sold to Dassault for $2.0 million or
approximately $3.60 per share. In the private equity transaction, we sold 1.9
million shares of our common stock for $6.84 million, or $3.60 per share, and
warrants to purchase an aggregate of 1.2 million shares of our common stock for
$60,000, or $0.05 per warrant. The warrants are exercisable for shares of our
common stock at a price of $6.50 per share.

    Net cash used by operating activities was $13.4 million for the year ended
December 31, 2001 as compared to $12.4 million for the year ended December 31,
2000. For the year ended December 31, 2001, net cash used by operations related
primarily to our net loss of $11.4 million. For the year ended December 31,
2000, net cash used by operations related primarily to our net loss, which
excludes the gain on the sale of the component software division.

    Net cash from investing activities for the year ended December 31, 2001 was
$516,000, comprised of $505,000 used for software and equipment purchases,
including $200,000 used for the Castalink technology acquisition, offset by the
$1 million gain on the sale of the component software division. This gain
resulted from the final settlement of the $1.0 million of funds escrowed by
Dassault in November 2000. Net cash provided by investing activities totaling
$16.1 million for the year ended December 31, 2000 which reflects $1.7 million
used for equipment purchases, $500,000 used for purchased computer software and
$100,000 paid for the Prescient assets, offset by net proceeds of $18.4 million
received in the sale of the component software division to Dassault.

                                       20
<Page>
    Net cash provided by financing activities was $11,000 for the year ended
December 31, 2001, related to proceeds from the exercise of common stock
options. Net cash provided by financing activities was $13.1 million for the
year ended December 31, 2000, primarily comprised of proceeds from the $6.9
million equity transaction in February 2000, proceeds from the $2.0 million
equity investment of Dassault in November 2000 and $200,000 from the exercise of
stock options. An additional $4.0 million was received from Dassault in the form
of notes payable that were advanced prior to the closing of the sale of the
component software division and which were repaid as an offset against the
purchase price for the division.

    Other than disclosed below, we have no other contractual cash obligations or
other commercial commitments. As a result, certain line items in the following
tabular disclosure regarding other contractual cash obligations, such as
long-term debt, capital lease obligations, unconditional purchase obligations
and commercial commitments, have been omitted.

    We believe that our current cash will be sufficient to meet our current
operating cash needs and that there will be no need to seek additional capital.
Our long-term liquidity, however, is materially dependent upon our ability to
achieve significant sales of our SCS--Envoy product line. If we fail to achieve
such sales or if our plans or assumptions change or are inaccurate or if we make
any acquisitions, we will need to seek additional capital through public or
private debt or equity offerings. There can be no assurance we will be able to
obtain any additional financing. If we raise funds through the issuance of
equity securities, the holders of new equity securities may have rights,
preferences or privileges senior to our common stock. If we obtain additional
funds through a bank credit facility or through issuance of debt securities or
preferred stock, this indebtedness or preferred stock would have rights senior
to the rights of our common stock, and their terms could impose significant
restrictions on our operations. If we are unable to obtain additional financing,
our business, financial condition and operating results will be significantly
impaired.

RECENT ACCOUNTING PRONOUNCEMENTS

    In June 2001, the Financial Accounting Standards Board ("FASB") issued SFAS
141, "Business Combinations," and SFAS 142, "Goodwill and Other Intangible
Assets." Under these new standards all business combinations initiated after
June 30, 2001 must use the purchase method of accounting. Intangible assets
acquired in a business combination must be recorded separately from goodwill if
they arise from contractual or other legal rights or are separable from the
acquired entity and can be sold, transferred, licensed, rented or exchanged,
either individually or as part of a related contract, asset or liability.
Goodwill and intangible assets with indefinite lives are not amortized but are
tested for impairment annually, except in certain circumstances, and whenever
there is an impairment indicator and all acquired goodwill must be assigned to
reporting units for purposes of impairment testing and segment reporting. SFAS
142 will be effective for the Company for the fiscal year beginning January 1,
2002. Management does not believe adoption of these statements will have any
impact on the Company's financial position, results of operations or cash flows.

    In August 2001, the FASB issued SFAS 143, "Accounting for Asset Retirement
Obligations." SFAS 143 requires entities to record the then fair value of a
liability for legal obligations associated with the retirement obligations of
tangible long-lived assets in the period in which it is incurred and the
corresponding cost capitalized by increasing the carrying amount of the related
asset. The liability will

                                       21
<Page>
continue to be accreted to the fair value at the time of settlement over the
useful life of the asset with the capitalized cost being depreciated over the
useful life of the related asset. If the liability is settled for an amount
other than the recorded amount, a gain or loss is recognized. The standard is
effective for the Company beginning fiscal year January 1, 2002. Management does
not believe that this statement will have an impact on the Company's financial
position, results of operations, or cash flows.

    In October 2001, the FASB issued SFAS 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets." SFAS 144 supersedes SFAS 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of," and replaces the accounting and reporting provisions for segments of a
business to be disposed of under Accounting Principles Board ("APB") Opinion
No. 30, "Reporting Results of Operations--Reporting the Effects of Disposal of a
Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring
Events and Transactions." SFAS 144 maintains the requirement that an impairment
loss be recognized for a long-lived asset to be held and used if its carrying
value is not expected to be recoverable from its undiscounted cash flows. SFAS
144 requires that long-lived assets to be disposed of, other than by sales, be
considered held and used until actually disposed of and requires that
depreciable lives be revised in accordance with APB Opinion No. 20, "Accounting
Changes." SFAS 144 also requires that long-lived assets to be disposed of by
sale be measured at the lower of carrying amount or fair value less selling
costs, but retains the requirement to report discontinued operations separately
from continuing operations and extends that reporting to a component of an
entity that has either been disposed of or is classified as held for sale. The
provisions of SFAS 144 are effective for the Company for the fiscal year
beginning January 1, 2002. Management does not believe adoption of this
statement will have an impact on the Company's financial position, results of
operations or cash flows.

CRITICAL ACCOUNTING POLICIES

    Our consolidated financial statements are impacted by the accounting
policies used and the estimates and the assumptions made by management during
their preparation. Critical account policies and estimates that most impact our
consolidated financial statements are those that relate to our revenue
recognition and intangibles. A summary of our significant accounting policies
can be found in the Notes to our Consolidated Financial Statements. Presented
below is a description of the accounting policies we deem critical to
understanding our consolidated financial statements.


    Revenue Recognition: We earn revenue primarily from license fees,
maintenance fees and professional services sold through direct sales. Our
license arrangements do not provide for a right of return. Maintenance fees
include training and consulting that is not rendered essential to the
functionality of the software. We also offer different levels of maintenance and
support arrangements, which provide the customer the right to receive error and
bug fix releases and version releases of the product made available during the
term of the maintenance contract.


    We recognize revenue in accordance with Statement of Position 97-2, Software
Revenue Recognition ("SOP 97-2"), as amended by SOP 98-9, and generally
recognize revenue when all of the following criteria are met as set forth in
paragraph 8 of SOP 97-2: (1) persuasive evidence of an arrangement exist; (2)
delivery has occurred; (3) the fee is fixed and determinable;
(4) collectibility is probable. We define each of these four criteria above as
follows:

    - PERSUASIVE EVIDENCE OF AN ARRANGEMENT EXISTS. It is our customary practice
      to have a written contract, which is signed by both the customer and us,
      or, in situations where a contract is not required, a customer purchase
      order has been received.

    - DELIVERY HAS OCCURRED. Our software may be either physically or
      electronically delivered to the customer. Delivery is deemed to have
      occurred upon the earlier of notification by the customer of acceptance or
      delivery of the software key. If undeliverable products or services exist
      in an arrangement that are essential to the functionality of the delivered
      product, delivery is not considered to have occurred until these products
      or services are delivered.

                                       22
<Page>
    - THE FEE IS FIXED OR DETERMINABLE. Our customers generally pay a per seat
      fee for our products. Fees are generally due within 30 days of product
      delivery. Fees payable to us pursuant to payment schedules that extend
      beyond our customary payment terms are deemed not fixed or determinable,
      and the revenue from such arrangements is recognized as payments become
      due.

    - COLLECTIBILITY IS PROBABLE. Collectibility is assessed on a
      customer-by-customer basis. We typically sell to customers with high
      credit ratings and solid payment practices. New customers are subjected to
      a credit review process in which we evaluate the customers' financial
      positions and ultimately their ability to pay. If it is determined form
      the outset of an arrangement that collectibility is not probable based
      upon our credit review process, revenue is recognized as cash payments are
      received.

    We allocate revenue on software arrangements involving multiple elements to
each element based on the relative fair value of each element. Our determination
of fair value of each element in multiple element arrangements is based on
vendor-specific objective evidence ("VSOE"). We limit our assessment of VSOE to
the price charged when the same element is sold separately. We have analyzed all
the elements included in our multiple element arrangements and determined that
we have sufficient VSOE to allocate revenue to maintenance and support services
and professional service of our license arrangements. We sell our professional
service separately, and have established VSOE on this basis. VSOE for
maintenance and support services is based on the customer's annual renewal rates
for these elements. Accordingly, assuming all other revenue recognition criteria
are met, revenue from license is recognized on delivery using the residual
method in accordance with SOP 98-9, and revenue from maintenance and support
services is recognized ratably over the respective term.

    Our professional services generally are not essential to the functionality
of the software. Our software products are fully functional upon delivery and
implementation and do not require any significant modification or alteration.
Customers purchase these professional services to facilitate the adoption of our
technology and dedicate personnel to participate in the services being
performed, but they may also decide to use their own resources or appoint other
professional service organizations to provide these services. Software products
are typically billed separately and independently from professional services,
which are generally billed either on a time-and-materials or a
milestone-achieved basis. We generally recognize revenue from professional
services as the services are performed.

    Accounts receivable is recorded net of allowance for doubtful accounts,
which totaled $203,000 as of December 31, 2001. We regularly review the adequacy
of our accounts receivable allowance after considering the size of the accounts
receivable aging, the ages of each invoice, each customer's expected ability to
pay and our collection history with each customer. We review any invoice greater
than 90 days past due to determine if an allowance is appropriate based on the
risk category using the factors discussed above. The allowance for doubtful
accounts represents our best estimate, but changes in circumstances relating to
accounts receivable may result in additional allowances or recoveries in the
near future.

    Intangibles: We review long-lived assets, including intangible assets for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. Recoverability of assets to
be held and used is measured by a comparison of the carrying amount of an asset
to the undiscounted future cash flow expected to be generated from the operation
of that asset. If the assets are considered to be impaired, the impairment to be
recognized is measured by the amount in which the carrying amount of the assets
exceeds the fair market value of the assets. An asset's fair market value will
be determined by future discounted net cash flows expected to be generated by
the asset. Assets to be disposed of are reported at the lower of the carrying
amount or fair value, less costs to sell. The Company did not recognize any
impairment in 2001 or 2000. As discussed above in "Recent Accounting
Pronouncements" we will adopt FAS No. 141 "Business Combinations" and FAS 142
"Goodwill and Other Intangibles" as of January 1, 2002. As a result, goodwill
and certain intangible assets will not be amortized, but instead, will be
reviewed for impairment at least annually, in accordance with the provisions of
this statement.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Stockholders
PlanetCAD Inc.:

    We have audited the accompanying consolidated balance sheets of PlanetCAD
Inc. and its subsidiary as of December 31, 2001, and the related consolidated
statements of operations, stockholders' equity and cash flows for the years
ended December 31, 2001 and 2000. These consolidated financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these consolidated financial statements based on our audits.

    We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of PlanetCAD
Inc. and its subsidiary as of December 31, 2001, and the results of their
operations and their cash flows for the years ended December 31, 2001 and 2000
in conformity with accounting principles generally accepted in the United States
of America.

                         PLANETCAD INC. AND SUBSIDIARY
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    (a) ORGANIZATION AND BASIS OF FINANCIAL STATEMENT PRESENTATION

    PlanetCAD Inc. ("PlanetCAD" or the "Company") was incorporated under the
laws of the State of Delaware on July 7, 1986 to design, develop, and market
three-dimensional modeling software. In November 2000, the Company's
shareholders approved plans to sell the assets of its component software
division to Dassault Systemes Corp. or its assignee ("Dassault") in a cash
transaction for $25.0 million, subject to certain price adjustments, and amended
Article I of the Company's restated certificate of incorporation to change its
name from Spatial Technology Inc. to PlanetCAD Inc. The Company consummated the
sale to Dassault and effected the name change on November 14, 2000. The net
assets and results of operations of the component software division have been
reclassified as discontinued operations and, accordingly, prior periods have
been restated.

    The accompanying consolidated financial statements include the accounts of
the Company and its subsidiary. All significant intercompany accounts and
transactions have been eliminated in consolidation.

    The preparation of the consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ significantly from those estimates.

    (b) EARNINGS (LOSS) PER SHARE

    Loss per share is presented in accordance with the provisions of Statement
of Financial Accounting Standards No. 128, Earnings Per Share (SFAS No. 128).
Under SFAS No. 128, basic earnings (loss) per share (EPS) excludes dilution for
potential common stock issuances and is computed by dividing earnings or loss
available to common stockholders by the weighted average number of common shares
outstanding for the period. Diluted EPS reflects the potential dilution that
would occur if securities or other contracts to issue common stock were
exercised or converted into common stock. Basic and diluted EPS are the same in
2001 and 2000, as all potential common stock instruments, consisting of common
stock options and warrants, are anti-dilutive due to the net losses from
continuing operations for each year.

    The following is a reconciliation of the numerators and denominators of the
basic and diluted EPS computations (in thousands, except per share data):

</Table>

    For all periods presented, 0 and 576,835 options and warrants for the years
ended December 31, 2001 and 2000 respectively were excluded from the diluted
loss per share calculation because their effect would be anti-dilutive.

    (c) CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investment instruments purchased
with an original maturity of three months or less to be cash equivalents.

    (d) OTHER COMPREHENSIVE INCOME OR LOSS

    Assets and liabilities of the Company's international subsidiary were
translated into U.S. dollars using current exchange rates in effect at the
balance sheet date, and revenue and expense accounts were translated using a
weighted average exchange rate during the year. Net exchange gains and losses
resulting from such translations are included as a separate component of
stockholders' equity as other comprehensive income or loss. Gains and losses
from foreign currency transactions, when applicable, are included in other
income (expense). The unrealized loss was realized in conjunction with the sale
of the component software division in 2000.

    (e) REVENUE RECOGNITION


    The Company recognizes revenue in accordance with the provisions of
Statement of Position 97-2, "Software Revenue Recognition" ("SOP 97-2"), which
requires that revenue for licensing, selling, leasing, or otherwise marketing
computer software be recognized when evidence of an arrangement exists, delivery
of the product has occurred, collectibility of the related receivable is assured
and the vendor's fee is fixed or determinable. In addition, revenue is
recognized for the multiple elements of software arrangements based upon vendor
specific objective evidence of fair value for each element. Accordingly, revenue
from products or services is recognized upon shipment of products or performance
of services. In December 1998, the American Institute of Certified Public
Accountants ("AICPA") issued SOP No. 98-9, "Modification of SOP No. 97-2,
Software Revenue Recognition, with


                                       31
<Page>

Respect to Certain Transactions." SOP No. 98-9 clarifies certain provisions of
SOP No. 97-2. Effective January 1, 1999, the Company adopted the provision of
SOP No. 98-9, and the impact on the Company's results of operations, financial
position or cash flows was not material.



    The Company's determination of the fair value of each element in multiple
element arrangements is based upon vendor-specific objective evidence ("VSOE").
The Company limits its assessment of VSOE to the price charged when the same
element is sold separately. The Company has analyzed all the elements included
in its multiple element arrangements and determined that it has sufficient VSOE
to allocate revenue to maintenance and support services and professional service
of its license arrangements. The Company sells its professional service
separately, and has established VSOE on this basis. VSOE for maintenance and
support services is based on the customer's annual renewal rates for the
elements. Accordingly, assuming all other revenue recognition criteria are met,
revenue from license is recognized on delivery using the residual method in
accordance with SOP 98-9, and revenue from maintenance and support serviced is
recognized ratably over the respective term. Training and consulting revenue is
recognized upon completion of the training or performance of services,
respectively. The Company's software products are fully functional upon delivery
and implementation and do not require any significant modification or
alteration. The Company does not provide extended payment terms to our
customers. The license fee arrangements do not provide for a right of return.


    (f) COST OF REVENUE

    Cost of revenue consists of operations, which include compensation for
operations personnel, cost of third-party software and direct costs incurred
when providing services. Operations employees are personnel charged in providing
training, maintenance, support and consulting services.

    (g) EQUIPMENT AND PURCHASED COMPUTER SOFTWARE

    Equipment is recorded at cost and depreciated using the straight-line method
over the estimated useful lives of the respective assets, which range from three
to seven years. Purchased computer software represents software enhancements
acquired from third parties, and is amortized over its estimated useful life of
three to seven years, beginning when the software is incorporated into the
Company's products.

    (h) STOCK-BASED COMPENSATION

    The Company accounts for its stock-based compensation plans using the
intrinsic value based method prescribed by Accounting Principles Board Opinion
No. 25, "Accounting for Stock Issued to Employees," and related interpretations
("APB 25"). The Company has provided pro forma disclosures of net earnings
(loss) and earnings (loss) per share as if the fair value based method of
accounting for these plans, as required by Statement of Financial Accounting
Standards No. 123, "Accounting for Stock-Based Compensation ("SFAS 123")," had
been applied.

    (i) IMPAIRMENT OF LONG-LIVED ASSETS

    The Company accounts for long lived assets under the provisions of Statement
of Financial Accounting Standards No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" ("SFAS 121")
which requires that long-lived assets and certain identifiable intangibles,
including goodwill, held and used by an entity be reviewed for impairment
whenever events or changes in circumstances indicate that the carrying value of
an asset may not be recoverable. An impairment loss is recognized when estimated
undiscounted future cash flows expected to be generated by the asset are less
than its carrying value. Measurement of the impairment loss is based on the fair
value of the asset, which is generally determined using valuation techniques
such as discounted present value of expected future cash flows.

    (j) RESEARCH AND DEVELOPMENT COSTS

    Costs to establish the technological feasibility of computer software
products are expensed as incurred. Generally, products are ready for sale upon
establishment of technological feasibility. Accordingly, no software development
costs have been capitalized by the Company in 2001 and 2000. Research and
development costs are expensed as incurred.

    (k) INCOME TAXES

    The Company accounts for income taxes under the provisions of Statement of
Financial Accounting Standards No. 109 "Accounting for Income Taxes" ("SFAS
109"). SFAS 109 requires the use of the asset and liability method of accounting
for income taxes. Under the asset and liability method, deferred income taxes
are recognized for the tax consequences of temporary differences by applying
enacted statutory rates applicable to differences between the financial
statement carrying amounts and the tax bases of existing assets and liabilities.

    (l) DISCONTINUED OPERATIONS

    The sale of the component software division resulted in a gain of $1.0
million, net of tax in 2000, and $17.4 million, net of tax in 2000. The results
of operations of the component software division through the date of the sale
are shown as income loss from discontinued operations in the consolidated
statements of operations.

    Summary operating results of the discontinued operations were as follows:

    (m) ADVERTISING COSTS

    Advertising costs are charged to expense when incurred and amounted to
$98,000 and $105,000 in 2001 and 2000 respectively.

(2) ACQUISITIONS AND IN-PROCESS RESEARCH AND DEVELOPMENT

    In July 2000, the Company acquired certain assets and liabilities of
Prescient Technologies, Inc. for total consideration of approximately $1.3
million, including $100,000 cash and 300,000 shares of the Company's common
stock. The acquisition was accounted for using the purchase method and,
accordingly, results of operations of Prescient have been included in the
Company's financial statements from the date of acquisition. The purchase price
was allocated to the assets and liabilities acquired based on their estimated
fair values, including $298,000 of accounts receivable, $209,000 of furniture

                                       33
<Page>
and equipment, $174,000 of other assets, and the assumption of $493,000 of
liabilities. In addition, the Company allocated $773,000 of the purchase price
to software costs and other intangible assets and $332,000 to in-process
research and development projects. The software costs and other intangible
assets will be amortized over 3 years. The Company charged the in-process
research and development to operations as of the date of acquisition as such
technology had not reached technological feasibility and had no probable
alternative future use by the Company.

    The summary table below, prepared on an unaudited pro forma basis, combines
the Company's consolidated results of operations with Prescient's results of
operations as if the acquisition took place on January 1, 2000 (in thousands,

(4) NOTES PAYABLE

    In September 2000, Dassault made a loan to the Company for $2 million of the
purchase price for the sale of the component software division in advance of the
closing of the transaction, which amount, including accrued and unpaid interest,
was repaid by the Company as an offset against the purchase price at the
closing. In November 2000, Dassault advanced an additional $2 million to the
Company, which was also repaid at the closing.

(5) STOCKHOLDERS' EQUITY

    PREFERRED STOCK

    In June 1996, the board of directors of the Company authorized, at their
discretion, the issuance of up to 2,500,000 shares of preferred stock in one or
more series and to fix the rights, preferences, and privileges of such series.
As of December 31, 2001, no shares of preferred stock were outstanding. On March
11, 2002, in connection with the adoption of the stockholder rights plan
described below, the Company designated 100,000 shares of preferred stock as
Series A Junior Participating Preferred Stock, no shares of which are
outstanding.

                                       34
<Page>
    STOCKHOLDER RIGHTS PLAN

    On March 8, 2002, the Company adopted a stockholder rights plan to protect
the Company and its stockholders from unsolicited attempts or inequitable offers
to acquire the Company's stock. The rights plan has no immediate dilutive effect
and does not diminish the Company's ability to accept an offer to purchase the
Company that is approved by the board of directors. The stockholder rights plan
was implemented through a dividend of one preferred share purchase right on each
outstanding share of the Company's common stock outstanding on March 21, 2002.
Each right will entitle stockholders to buy one one-thousandth of a share of
Series A Junior Participating Preferred Stock at an exercise price of $5.00. The
rights will become exercisable (with certain limited exceptions provided in the
rights agreement) following the 10th business day after: (a) a person or group
announces that it has acquired beneficial ownership of 15% or more of the
Company's outstanding common stock or (b) a person or group announces the
commencement of a tender offer the consummation of which would result in the
beneficial ownership by the person or group of 15% or more of the Company's
outstanding common stock. The buyer would not be entitled to exercise rights
under the rights plan. The effect of the rights plan is to discourage
acquisitions of more than 15% of the Company's common stock without negotiations
with the Company's board of directors. The Company can redeem the rights for
$.0001 per right at certain times as provided in the rights agreement. The
rights expire on March 8, 2012.

    STOCK OPTIONS

Incentive Plan (the "2000 Plan"). Up to 2,000,000 shares of common stock may be
issued pursuant to the 2000 Plan. Under the 2000 Plan, the Company may issue
incentive stock options, which are granted with exercise prices equal to the
fair value of the common stock on the date of grant. Vesting and option terms,
which may not exceed ten (10) years from the date of grant, are determined by
the board of directors at the time of grant. As of December 31, 2001, options to

may issue nonqualified stock options, which are granted with exercise prices
equal to the fair value of the common stock on the date of grant. Vesting and
option terms, which may not exceed ten (10) years from the date of grant, are
determined by the board of directors at the time of grant. As of December 31,
2001, options to purchase 262,250 shares of common stock under the 1998 Plan
were outstanding at a weighted average exercise price of $3.034.

    In June 1996, the Board of directors of the Company approved the 1996 Equity
Incentive Plan (the "1996 Plan"). Up to 1,350,000 shares of common stock may be
issued pursuant to the 1996 Plan. Under the 1996 Plan the Company may issue
incentive stock options and nonqualified stock options. Incentive stock options
are granted with exercise prices equal to or greater than the fair value of the
common stock on the date of grant, vest over a four-year employment period, and
are exercisable over a maximum ten-year employment period. The Company also
grants nonqualified stock options under the 1996 Plan that vest over a four-year
period or earlier upon the attainment of specific performance objectives, and
are exercisable over a maximum ten-year period or upon attainment of such
objectives. As of December 31, 2001, options to purchase 664,276 shares of
common stock under the 1996 Plan were outstanding at a weighted average exercise
price of $2.360.

    In June 1996, the Board of directors approved the 1996 Non-Employee
Directors' Stock Option Plan (the "Directors' Plan"). Up to 250,000 shares of
common stock may be issued pursuant to the Directors' Plan. Stock options
granted under the Directors' Plan are granted with exercise prices equal to or
greater than the fair value of the common stock on the date of grant, vest over
a four-year period and are exercisable over a ten-year period from date of
grant. As of December 31, 2001, options to

                                       35
<Page>
purchase 220,270 shares of common stock under the Directors' Plan were
outstanding at a weighted average exercise price of $3.192.

    In August 1996, the Company's Board of directors approved the termination,
effective upon the Company's initial public offering, of the Amended and
Restated 1987 Stock Option Plan (the "1987 Plan"). Under the 1987 Plan the
Company issued incentive stock options and nonqualified stock options. Incentive
stock options were granted with exercise prices equal to or greater than the
fair value of the common stock on the date of grant, vest over a four-year
employment period, and are exercisable over either a five-year or ten-year
employment period. The Company also granted nonqualified stock options under the
1987 Plan that vest over a four-year period or upon the attainment of specific
performance objectives, and are exercisable over a five-year period or upon
attainment of such objectives. As a result of such termination, no additional
options may be issued under the 1987 Plan. The options to purchase 16,601 shares
of common stock at a weighted average exercise price of $4.880 outstanding as of
December 31, 2001, will remain exercisable until they expire or terminate
pursuant to their terms.

    In July 2000, the Company entered into a consulting agreement with a former
non-employee director. Under this agreement, the Company agreed to issue options
to purchase shares of common stock in addition to the non-discretionary grant of
options to purchase 15,000 shares of common stock that he received upon his
election to our board of directors. Of the additional grant, 25,000 options were
to vest in equal annual increments over four years, and the remaining 40,000
options were to vest on the fifth anniversary of the date of the option grant.
The options expired, however, one year after service for the Company terminated.

    In August 2001, the Company issued options to a non-employee director. In
addition to the non-discretionary grant of options to purchase 15,000 shares of
common stock related to his election to the board of directors, the Company
granted 75,000 options that will vest on the seventh anniversary of the date of
the option grant.

    In November 2000 and in connection with the Dassault transaction, the
Company provided early vesting of options held by employees of the component
software division who were hired by Dassault if they continued to work for
Dassault through November 14, 2001. The modification of the previously granted
stock option awards resulted in a new measurement date but no additional
compensation expense since the exercise price of the options exceeded the fair
value of the Company's common stock on the modification date.

    In December 2000, the Company entered into separation agreements with three
former employees. The terms of these agreements included an aggregate of
$120,000 in severance payments as well as $250,000 in a bonus payment and
$250,000 in exchange for a non-competition agreement. In addition, the Company
issued 101,000 non-qualified, fully vested, stock options pursuant to these
agreements, priced as of their separation dates, with contractual terms ranging
from five to ten years. The fair value of the options was insignificant at the
date of issuance.

EMPLOYEE STOCK PURCHASE PLAN

    In June 1996, the board of directors approved the Employee Stock Purchase
Plan. Up to 300,000 shares of common stock may be issued pursuant to the plan.
Employees may elect to withhold up to 15% of their compensation for the purchase
of the Company's common stock. The amounts withheld

                                       37
<Page>
are used to purchase the Company's common stock at a price equal to 85% of the
fair value of shares at the beginning or end of each purchase period. During
2001 and 2000 the Company issued 25,458 and 71,219 shares at average prices of
$0.47 and $2.32, respectively.

</Table>

    At December 31, 2001, the Company had net operating loss carryforwards for
regular income tax purposes of approximately $24.6 million, which if not
utilized expire in the years 2003 through 2021. The net operating loss
carryforwards at December 31, 2001 are subject to limitation under Section 382
of the Internal Revenue Code. The Company has provided a valuation allowance for
the entire deferred tax balance due to uncertainty of the realization of the
asset.

    The Company also has research and experimentation credit carryforwards for
income tax purposes available totaling approximately $1.6 million, which if not
utilized expire in the years 2003 through 2021. These credit carryforwards may
also be subject to limitation under Section 382 of the Internal Revenue Code.

(7) COMMITMENTS AND CONTINGENCIES

    The Company leases its office facilities and various office equipment under
noncancelable operating leases. Future minimum rental payments on these leases
are as follows (in thousands):

<Table>

</Table>

    Rent expense was approximately $1.1 million and $613,000 in 2001 and 2000,
respectively.

    The Company executed a long-term development agreement with Three-Space
Limited, a United Kingdom corporation (TSL), in 1989 (the "1989 Development
Agreement") obligating the Company to pay approximately $30,000 per month for
specified research and marketing activities. In connection with the Prescient
acquisition, the Company terminated the 1989 Development Agreement and entered
into a Software Consulting Agreement with substantially the same financial
obligation to the Company. Approximately $200,000 in expenses were incurred
under the 1989 Development Agreement and the software consulting agreement
during 2000. In connection with the sale of the component software division, the
Software Consulting Agreement was assigned to Dassault.

                                       39
<Page>
    The Company has entered into various licensing agreements, which require the
Company to pay royalties on each sale of the licensed software products. Royalty
expense under these agreements is included in cost of sales and totaled
approximately $369,000 and $265,000 in 2001 and 2000, respectively.

    The Company is involved in various claims and legal actions arising in the
ordinary course of business. In the opinion of management, the ultimate
disposition of these matters will not have a material adverse effect on the
Company's financial position, results of operations or cash flows.

(8) CONCENTRATIONS OF CREDIT RISK

    The Company is exposed to potential concentrations of credit risk from its
accounts receivable with its various customers. The Company's accounts
receivable are from both large multinational corporate customers and smaller
companies in a variety of industries, with no concentration in a single
industry. However, the Company is subject to credit risk due to economic events
or circumstances in the various international and domestic markets in which the
Company operates. To reduce this risk, the Company evaluates the
creditworthiness of its customers prior to the shipment of software or
performance of services. During 2000, the Company had one customer that
accounted for 13% of its total revenue. The Company did not have any customer
that accounted for 10% of its total revenue for the year ended December 31,
2001.

(9) RELATED PARTY TRANSACTION

    In June 2001, the Company acquired software and equipment from an entity,
which had a significant investor affiliated with a member of the Company's board
of directors, for total consideration of approximately $265,000, including
$200,000 cash and 125,000 warrants to purchase the Company's common stock. The
warrants, which have an exercise price of $1.00 and expire on June 1, 2004, were
valued using the Black-Scholes option pricing model assuming no dividends, risk
free interest rate of 4.55%, volatility of 180% and life of 3 years.

(10) RESTRUCTURING COSTS


    During the third quarter of 2001, the Company implemented a restructuring
plan to reduce operating expenses and strengthen both its competitive and
financial positions by eliminating certain employee positions and reducing
office space and related overhead expenses. Overall expense reductions were
necessary both to lower existing cost structure and to reallocate resources to
pursue future operating strategies in response to declining revenue and other
performance measures during 2001. Restructuring charges primarily consisted of
$623,000 for severance and termination costs associated with the reduction in
force of 21 employees, all of which were paid during 2001. In connection with
the restructuring, the Company accrued an additional $400,000 in lease
abandonment costs, $245,000 of which was paid during 2001. The remaining
$155,000 represents costs due over the next four years, which were not offset by
sublease income. Each quarter, the Company expects to save $725,000 in salary
and benefits expense, $75,000 in facility related expenses and $150,000 in
consulting costs.


(11) SUBSEQUENT EVENTS

    Beginning in December 2001, PCD Investments, LLC, which has acquired
approximately 15% of our outstanding common stock since October 2001 and is our
largest stockholder, has made various proposals to purchase our outstanding
shares of common stock, including a potential hostile tender offer. PCD
Investments subsequently announced that it did not plan to commence the tender
offer, but that it intended to nominate at the 2002 annual meeting six
individuals to serve as members of our board of directors.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

    Section 16(a) of the Exchange Act requires our directors and executive
officers, and persons who own more than 10% of a registered class of our equity
securities, to file with the Securities and Exchange Commission initial reports
of ownership and reports of changes in ownership of our common stock and other
equity securities. Executive officers, directors and holders of greater than ten
percent of our common stock are required by regulations of the Securities and
Exchange Commission to furnish us with copies of all Section 16(a) reports they
file.

    To our knowledge, based solely upon a review of the copies of such reports
furnished to us and written representations that no other reports were required
to be filed during the fiscal year ended December 31, 2001, all of our executive
officers, directors and holders of greater than 10% of our common stock complied
with the applicable filing requirements of Section 16(a), except that Mr. Chuck
Bay, a former non-employee director, failed to file a Form 5.

<Page>
(2) For purposes of this table, valuation is based on vested options for each
    named executive officer. Certain options granted to such individuals include
    early exercise provisions, the value of which is not included in this table.

COMPENSATION OF DIRECTORS

    Each of our directors is entitled to be reimbursed for reasonable
out-of-pocket expenses incurred in connection with attendance at each meeting of
the board. Additionally, each of our non-employee directors receives $1,000
compensation for each regular or special meeting of the board at which he is in
attendance and $500 compensation for each committee meeting of the board at
which he is in attendance. In months requiring multiple board meetings,
directors have accepted a $1,000 monthly stipend covering all board meetings
during a month in lieu of the $1,000 fee per meeting.

    Each of our non-employee directors also receives stock option grants
pursuant to the 1996 Non-Employee Directors' Stock Option Plan. Only directors
who are not otherwise our employees or affiliates are eligible to receive such
options. Each non-employee director is automatically granted a non-discretionary
option to purchase 15,000 shares of our common stock on the date such
non-employee director is elected to the board. Additionally, on the date of each
annual meeting of our stockholders subsequent to election, each non-employee
director who has been a non-employee director continuously for the preceding
year is automatically granted an option to purchase 7,500 shares of our common
stock. Each other non-employee director is automatically granted an option to
purchase a number of shares of our common stock equal to 7,500 multiplied by a
fraction, the numerator of which is the number of days served as a non-employee
director and the denominator of which is 365. The exercise price of options
granted to non-employee directors is the fair market value of the common stock
on the date of grant. Options granted pursuant to the plan vest in four equal
annual installments beginning one year from the date of grant and are
immediately exercisable, subject to repurchase by us prior to the vesting of
such shares upon the optionee's cessation of service with us.

    We entered into arrangement with James A. Fanella, one of our non-employee
directors, upon his election to the board of directors. Under the arrangement,
we granted to Mr. Fanella an option to purchase 40,000 shares of our common
stock in addition to the non-discretionary option grant to purchase 15,000
shares of our common stock. The additional option to purchase 40,000 shares of
our common stock vests in full in October 2008. However, the vesting of the
additional option may be accelerated based on the achievement of certain
performance goals.

EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT AGREEMENTS

    We entered into a separation and release agreement with Mr. Sowar that was
made effective as of October 1, 2001. Under the terms of the agreement, we paid
Mr. Sowar for all accrued and unused vacation through October 1, 2001 and a lump
sum payment of $200,000. In addition, we agreed to pay the premium cost of
continuing Mr. Sowar's medical, vision and dental benefits through
September 30, 2002, or until Mr. Sowar becomes eligible for coverage under
another plan. As part of the agreement, we amended the terms of Mr. Sowar's
stock option grants to provide that all of Mr. Sowar's options would become
fully exercisable on October 8, 2001 and remain exercisable until October 1,
2006. We also forgave the principal and interest on a loan payable to us in the
amount of $34,688. The lump sum payment, continuation of insurance benefits,
option provisions and forgiveness of the loan were all conditioned on Mr. Sowar
not exercising has right to revoke the agreement. Mr. Sowar agreed to provide
consulting services to us for a period of six months and not to compete with us
during that time. Finally, we entered into with Mr. Sowar a mutual release and
waiver of any current or future claims that one of us may have against the
other.

    We entered into change in control agreements with Mr. Hushbeck and
Ms. Godesiabois effective November 2001. The agreements expire by their terms in
November 2002, unless our board of directors exercises its right to extend the
terms for an additional year. The agreements provide that if

                                       45
<Page>
Mr. Hushbeck and Ms. Godesiabois' employment is continued during the one-year
period after a change in control or threatened change in control, their
employment must be continued on terms that are at least as favorable as the
terms of their employment prior to the change in control or threatened change in
control. If their employment is not continued for the entire one-year period
following a change in control or threatened change in control, Mr. Hushbeck and
Ms. Godesiabois could become entitled to receive as severance payment all
accrued and unused vacation time, continuation of their medical, vision and
dental benefits for a period of six months, or until they become eligible for
coverage under another plan, lump-sum payments equal to four months of their
respective salary rate in effect at that time, accelerated vesting of their then
outstanding options and an extension to 30 months of the period during which
they can exercise certain of their options. Mr. Hushbeck and Ms. Godesiabois
only become entitled to receive the severance if their employment is terminated
without cause or if they resign for good reason. In exchange for the foregoing
accommodations, Mr. Hushbeck and Ms. Godesiabois agreed not to compete with us
or otherwise interfere with our business for a period of one year following the
termination of their employment with us for any reason.

    We also entered into a change in control agreement with Mr. Bracking
effective November 2001. Mr. Bracking's change in control agreement was
superseded by a separation and release agreement that we entered into with
Mr. Bracking when his employment with us terminated in January 2002.
Mr. Bracking's change in control agreement provided that if Mr. Bracking's
employment was continued during the one-year period after a change in control or
threatened change in control, his employment would be continued on terms that
were at least as favorable as the terms of his employment prior to the change in
control or threatened change in control. His agreement further provided that if
his employment was not continued for the entire one-year period following a
change in control or threatened change in control, Mr. Bracking could become
entitled to receive as severance payment all accrued and unused vacation time,
continuation of his medical, vision and dental benefits for a period of twelve
months, or until he became eligible for coverage under another plan, lump-sum
payments equal to six months of his respective salary rate in effect at that
time, accelerated vesting of his then outstanding options and an extension to 36
months of the period during which he could exercise certain of his options.
Mr. Bracking only was entitled to receive the severance if his employment was
terminated without cause or if he resigned for good reason. In exchange for the
foregoing accommodations, Mr. Bracking agreed not to compete with us or
otherwise interfere with our business for a period of one year following the
termination of his employment with us for any reason.

    We entered into a separation and release agreement with Mr. Bracking that
was made effective as of January 25, 2002. Under the terms of the agreement, we
paid Mr. Bracking for all accrued and unused vacation through January 25, 2002
and severance payments totaling $65,625. We paid one-half of the total severance
amount in a lump-sum payment and the other half in seven semimonthly
installments. In addition, we agreed to pay the premium cost of continuing
Mr. Bracking's medical, vision and dental benefits through July 31, 2002. As
part of the agreement, we agreed that his option under his incentive option
agreement dated December 14, 2000 would remain exercisable until January 25,
2003. Mr. Bracking agreed not to compete with us for a period of six months from
the effective date of the agreement. Finally, we entered into with Mr. Bracking
a mutual release and waiver of any current or future claims that one of us may
have against the other.

ITEM 12.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

    The following is a brief description of the transactions entered into during
the last two years between us and the related parties identified below.

COMPENSATION OF OUR NEW PRESIDENT AND CEO

    Mr. Hushbeck was appointed as our President and Chief Executive Officer in
January 2002 and has served as a director since February 2002. For the fiscal
year 2002, we have agreed to pay Mr. Hushbeck a salary of $200,000. In February
2002, we granted Mr. Hushbeck an option to purchase 175,000 shares of our common
stock at $0.19 per share. Subject to the terms of his change in control
agreement described above, the option granted in 2002 will vest and become
exercisable as to 25% of the underlying shares of common stock in
February 2003. The remaining shares will vest and become exercisable in equal
installments at the end of each calendar quarter for the three years following
February 2003.

ISSUANCE OF WARRANTS TO 5% STOCKHOLDER AND DIRECTOR'S AFFILIATE

    Under the terms of an asset purchase agreement dated June 1, 2001, we
purchased certain supply chain solution software and related assets from
Capstone Ventures and AI Research Corporation. As consideration for the
purchased assets, we paid Capstone Ventures and AI Research Corporation a total
of $200,000 and issued them warrants to purchase up to 125,000 shares of our
common stock for $1.00 per share. Of that consideration, we issued warrants to
purchase 88,250 shares of common stock to Capstone Ventures and paid them
$76,130. Capstone Ventures holds shares of our common stock equal to more than
5% of our total outstanding common stock, and Mr. Fischer, our chairman of the
board, is the president of the general partner of Capstone Ventures. The
warrants expire on June 1, 2004. Capstone Ventures and AI Research acquired the
assets on March 12, 2001 when they foreclosed on secured promissory notes issued
by Castalink that were in default. In total, Capstone Ventures invested more
than $2,000,000 in Castalink through various debt and equity financings.

COMPONENT SOFTWARE DIVISION DISPOSITION

    On November 14, 2000, we sold our component software division to a
subsidiary of Dassault Systemes Corp., which owns more than 5% of our common
stock, for approximately $24.5 million. The sale was effected pursuant to a
purchase agreement dated July 4, 2000, as amended September 2, 2000, among us,
Spatial Components, LLC, and Dassault, pursuant to which we formed Spatial
Components as a wholly owned subsidiary and capitalized it with all of the
assets and certain of the liabilities of our component software division. At the
closing of the sale, we transferred all of the membership interests in Spatial
Components to Spatial Corp., a wholly owned subsidiary of Dassault and the
assignee of Dassault under the purchase agreement. Upon the completion of the
transfer, Dassault, through its wholly owned subsidiary Spatial Corp., became
the sole owner of Spatial Components and, therefore, the component software
division.

INTELLECTUAL PROPERTY AGREEMENTS ENTERED INTO WITH DASSAULT

    As part of the sale of our component software division, we obtained licenses
from Dassault for the right to use certain Dassault software and other
intellectual property, and, in exchange, we licensed to Dassault the right to
use software that we did not sell to Dassault. In order to define our
relationship with Dassault, we entered into the intellectual property agreements
described below. Each of the following intellectual property agreements
represents a direct relationship, or indirect relationship through a wholly
owned subsidiary of Dassault, between the parties identified. Under the terms of
a settlement agreement with Dassault dated on or about December 19, 2001, all of
the following agreements, except the IntraVision license agreement, were
terminated. The IntraVision agreement remains in effect under its original
terms.

CROSS-LICENSE AGREEMENT

    Under the Cross-License Agreement, Dassault granted us a perpetual,
non-exclusive license to use certain computer software programs sold to Dassault
with the component software division, including ACIS and IVSDK. In consideration
for Dassault's license, we agreed to pay Dassault a royalty equal to a specified
percentage of our net revenue resulting from any products or services we sold
that utilized or were based on the Dassault software. The royalty was subject to
a minimum annual payment. We agreed to pay a separate royalty to Dassault in
connection with the distribution of IVSDK and the ACIS Open Viewer Plug-Ins
application software.

    We agreed to grant Dassault a perpetual, royalty-free, non-exclusive license
to use and modify internally certain of our data translation and data exchange
application software, including IGES and STEP Toolkits. Dassault also had the
right to distribute the software in run-time or object code format as component
products and/or stand-alone software products or in connection with providing

                                       49
<Page>
application service provider and other enterprise services to Dassault's
customers. Dassault agreed to develop CATIA/SAT translator software and grant us
a perpetual, royalty-free, non-exclusive license to use and modify the
translator software as an underlying application for our Internet services and
to distribute run-time versions of the translator software in connection with
our Internet services. Each party agreed to provide the other with maintenance
in connection with the licensed software.

CO-BRANDING AGREEMENT

    Under the Co-Branding Agreement, we agreed with Dassault to jointly market
translation and healing application services, similar to those offered on our
Web sites under the product name "3Dshare.com," via one or more Dassault Web
sites. We granted Dassault a royalty-free, non-exclusive license to use our Web
service infrastructure software for the purpose of providing the Co-Branded
Service to its customers. We agreed to host the Co-Branded Service and made the
Co-Branded Service accessible from any Dassault Web site that Dassault
requested. In consideration of the infrastructure license and performance of our
obligations under the Co-Branding Agreement, we were entitled to a percentage of
the net revenues derived from the sale of the Co-Branded Service.

SERVER SOFTWARE LICENSE AGREEMENT

    Under the Server Software License Agreement, we granted Dassault a
non-transferable, non-exclusive license to certain of our Web site
infrastructure applications software. Dassault had the right to use and modify
the Server Software internally to provide application services and related
Internet services to its customers. In addition, Dassault had the right to
distribute the Server Software in connection with those Dassault software
products and services into which it had incorporated the Server Software. In
consideration for the license of the Server Software, Dassault agreed to pay us
a royalty equal to a specified percentage of the net revenue resulting from the
sale of any products or services offered by Dassault incorporated or facilitated
by the Server Software. Dassault also agreed to pay us an initial license fee
for use of the Server Software, which offset a percentage of the royalty
payments due from Dassault. In consideration for the license fee and royalty
payments, we agreed to provide Dassault with maintenance and support services
for the Server Software for four years.

WEB SERVICES AGREEMENT

    Under the Web Services Agreement, Dassault granted us the right to market
and distribute, via our 3Dshare.com and PlanetCAD.com Web sites, certain Web
services using Dassault's application software. We agreed to assist Dassault in
adapting these applications for Internet use by providing a fixed amount of
technical support at no charge to Dassault and further support, if necessary, at
a discount from our standard consulting rate. We also agreed to develop the Web
pages and functions needed to market and distribute the agreed upon Dassault Web
services at our own expense. We agreed to spend a minimum percentage of the
revenue generated through the distribution of each Web service on advertising
programs related to that service for 30 months after the implementation of each
service and a minimum amount on advertising in the first year of each service.
As consideration for marketing and distributing the Web services, we received a
percentage of net revenues generated by sales of the Web services on our Web
sites.

JOINT SOFTWARE LICENSE AGREEMENT

    Under the Joint Software License Agreement, we granted Dassault a perpetual,
royalty-free license to use, modify and distribute certain translator and
healing software jointly developed by us and certain third parties and to use
and distribute certain software licensed to us by certain third parties. The
license was exclusive to Dassault for use of the jointly developed software as
component products and non-exclusive for all other purposes. We agreed to
provide Dassault with maintenance and support services for the Joint Software
for five years from the date of the agreement at no cost to Dassault.

                                       50
<Page>
MASTER SOFTWARE RESELLER AGREEMENT

    Under the Master Software Reseller Agreement, we granted Dassault a
non-exclusive, non-transferable license to market, promote, reproduce for
distribution, distribute and sublicense certain software products and to use a
reasonable number of copies of those products for demonstration and training
purposes only. We also agreed to provide Dassault with reasonable quantities of
standard product marketing materials and product related training.

INTRAVISION LICENSE AGREEMENT

    Under the IntraVision License Agreement, Dassault granted us a worldwide,
exclusive license to use, maintain, support, access and reproduce the
IntraVision source code for the purposes of developing and offering to our
customers end-user products. The license does not permit us to create software
that is similar to or that competes with the IVSDK. In consideration of the
exclusive IntraVision distribution and source code development licenses granted
by Dassault, we agreed to pay to Dassault certain royalties relating to the net
revenue recognized by us as a result of the licenses.

ISSUANCE OF SHARES TO DASSAULT

    On November 14, 2000, we issued 555,556 shares of common stock to Dassault
for a purchase price of $2 million, or approximately $3.60 per share, pursuant
to the terms of a share purchase agreement, dated as of November 14, 2000, by
and between us and Dassault.
