     FIELD OF THE INVENTION 
       [0002]    The present invention relates generally to automated design of custom decorative stonework. 
       DESCRIPTION OF THE RELATED ART 
       [0003]    In the construction industry, decorative stonework has been common feature for a number of years. Larger and larger portions of stone are used in the construction of buildings and houses. Decorative stonework can be made by being cut from natural stone, cut from man-made materials, cast from molds, extruded or any combination of these techniques. Of these techniques, one of the most economical is casting using molds. Generally speaking, casting the stonework allows the aesthetics associated with decorative stonework to be preserved while reducing the overall cost. 
         [0004]    The process of manufacturing cast decorative stonework typically involves pouring a limestone-based material into a mold and allowing it to harden. Once the material has hardened it is removed from the mold as a manufactured decorative stonework piece. 
         [0005]    In some instances, a product may be formed of a single piece. However, more typically, more complex products, such as door frames, are not molded out of one continuous piece of manufactured stone. Instead, several pieces are assembled, usually at the job site, to yield the structure. The molds, then, are usually for the smaller components of the large whole product. 
         [0006]    Architecture is a high art form that has been around since earliest days. The Romans and Greeks were master architects. These groups adopted certain stylistic features that were associated with their architecture. In the traditional organizational scheme, architectural features are each given certain titles. For example, Doric, Ionic, and Corinthian columns are examples of Greco-Roman architectural features. Doric columns are least ornate of the three, having a plain shaft and a simple cap. Ionic columns are more ornate, having flutes caved into the shaft and a more ornate cap, such as scrolls. The Corinthian columns are the most ornate, usually with an extremely ornate cap. However, even through these architectural features accurately describe the features of a structure, the average layperson may not be able to describe a Doric column, let alone know the name of the feature. 
         [0007]    The customer is often a layperson and at the start of a project may not even know specifically what feature he or she desires. In fact, most laypersons would typically have only a holistic knowledge or a feel for what he or she wants. Traditional organizational schemes, though, may not necessarily provide a logical correlation to the average layperson. 
         [0008]    To alleviate the problem associated with logical associations, it would be desirable to have a database organizational scheme can be employed to better assist a lay customer or a professional in choosing the decorative stonework associated with desired architectural features. 
         [0009]    Several problems exist with the design, manufacture, and assembly of manufactured decorative stonework. For a given manufacturer of stone work, the molds can number in the tens of thousands. Changing the proportions of a given architectural feature can be cumbersome. There can be physical limitation as well as aesthetic considerations. Also, by changing the proportions of a given feature, the molds utilized to make the parts that compose the given architectural feature may have to be changed. Compounding the complexity of this problem is the fact that most decorative stonework products are custom designed to fit individual customer&#39;s tastes at the time a structure is designed. The decorative stonework products must also meet size and structural requirements dictated by other, non-stonework products (such as a wooden entry door) or natural geographic features of the site. Thus, oftentimes, no two decorative stonework products will be exactly alike. 
         [0010]    The parameters required for designing decorative stonework may not be known until the time a design for the entire structure is substantially complete. Nevertheless, decorative stonework must usually be incorporated into the design of a structure at the concept stage or it may be impractical to add later. Thus, the ability to design decorative stonework products at a very early stage of the conceptualization of a structure extremely quickly, from sometimes incomplete parameters, at least to the point that the appearance of the decorative stonework products in conjunction with the structure can be determined and the cost reliably estimated can be the difference between the structure ultimately including or not including any decorative stonework. 
         [0011]    Decorative stonework is typically very heavy. It can also be prone to damage during transportation if not properly packaged or unnecessarily handled. Typically, it will not be possible to pre-assemble the components at the stonework manufacturer&#39;s facility to ensure proper fit. To maintain an economical product, it is necessary to design and manufacture the components for the custom decorative stonework product, which may be one-of-a-kind, from tens of thousands of parts and their molds in an almost unlimited number of sizes, configurations and styles to fit with an unlimited number of structural designs. Then, all the components and their supporting documentation must be transported to the job site in all the correct sizes and at the right time. 
         [0012]    Therefore, there is a need for a method and/or apparatus for facilitating and at least partially automating the process of selection, identification, design and manufacturing of custom decorative stonework products that at least addresses some of the problems associated with conventional methods and apparatuses. 
       SUMMARY OF THE INVENTION 
       [0013]    The present invention provides a method for designing custom decorative stonework. At least one unit of a plurality of units is selected, wherein each unit of the plurality of units at least corresponds to an architectural feature, and wherein each unit of the plurality of units comprises a plurality of parts. At least a primary view is selected, wherein the primary view is at least the overall shape of the at least one unit. At least one profile of a plurality of profiles is selected, wherein each profile of a plurality of profiles corresponds to at least a primary cross-sectional view of the at least one unit. At least one dimension of a plurality of dimensions is input, wherein the at least one dimension is at least a physical dimension of the at least one unit. At least one dimension corresponding to a unit size is parametrically calculated, wherein calculating the at least one dimension further comprises at least determining relative sizes of the plurality of parts of the at least one unit. Also, at least one scaled drawing is generated, wherein the scaled drawing at least has numbers that corresponds to the plurality of parts of the at least one unit.

     DETAILED DESCRIPTION 
       [0030]    In the following discussion, numerous specific details are set forth to provide a thorough understanding of the present invention. However, those skilled in the art will appreciate that the present invention may be practiced without such specific details. In other instances, well-known elements have been illustrated in schematic or block diagram form in order not to obscure the present invention in unnecessary detail. 
         [0031]    Referring to  FIG. 1  of the drawings, the reference numeral  100  generally designates an improved organizational structure. The improved organizational structure  100  comprises a unit description  102 , part descriptions  104 , and profile descriptions  106 . 
         [0032]    When either a professional or a customer begins the process of choosing stonework, typically there is a first association to a specific item, such as a window. This first association is designated as a unit  102 . The unit  102  can be either a very simple or a complex item ranging from a simple feature, such as a window frame, to more complex features, such as gazebos and staircases. 
         [0033]    As it is well known, decorative stonework products are often not composed of a single, continuously molded block. Instead, to maximize the ability to create numerous varieties of units  102  while attempting to minimize costs, individual components or parts  104  are utilized. These parts are sometimes interchangeable and, thus, are capable of being used for a number of units. Furthermore, the parts  104  can be increased in size to create a large individual unit. Therefore, in the improved organizational scheme  100 , each unit  102  is subdivided into numerous parts  104 . Some parts, however, are not properly interchangeable with other parts either for physical or for aesthetic reasons. 
         [0034]    To increase the appeal of each of the units  100  and to include as many architectural styles as is possible, each part  104  has an associated profile  106 . The profile  106  is typically a vertical or horizontal cross-sectional view of a given part  104 . The shapes associated with crown molding are one example of such a profile feature. With crown molding, a piece of wood or stonework is shaped to have curves or shapes on the surface. A cross-sectional view of the crown molding would be a profile. Also, profiles can also be overall views if the surface contains more intricate molded carvings, such as carved leaves. 
         [0035]    By creating the associative database, a lay customer or professional is more capable of choosing desired features in stonework. Instead of sorting through either pictures of buildings or of sets of architectural features, a customer or professional can look through components or units  102  of a design scheme. By allowing a customer, specifically, to sort through the varieties of stonework available by unit  102 , the attention of the customer will more likely be retained. Preservation of a customer&#39;s attention clearly can preserve a possible sale that would provide a benefit to the customer and to the manufacturer/retailer. 
         [0036]    Referring to  FIG. 2  of the drawings, the reference numeral  200  generally designates an example of a unit. The unit comprises a first part  202 , a second part  204 , a third part  206 , a fourth part  208 , a fifth part  210 , a sixth part  212 , a seventh part  214 , and an eighth part  216 . 
         [0037]    The unit  200  is an example of a stone circle top door frame. The door frame of the unit  200  is not composed of a single, continuous piece of manufactured stone. Instead, the door frame of the unit  200  is composed of eight distinct parts  202 ,  204 ,  206 ,  208 ,  210 ,  212 ,  214 , and  216 . Each of the eight parts  202 ,  204 ,  206 ,  208 ,  210 ,  212 ,  214 , and  216  can vary in size depending on the dimensions of the door frame itself. 
         [0038]    Moreover, the style of the door frame of the unit  200  can be changed by interchanging some parts. For example, if a customer chooses to have an eyebrow door frame instead of a circular door frame, as shown in  FIG. 2 , then most of the original parts can be retained. The difference between an eyebrow door frame and a circular door frame is the arc across the top of the frame. The top of the circular door frame has a radius equal to one half the distance between the sides of the doorframe, whereas the top of an eyebrow doorframe is larger than the one half the distance between the sides of the doorframe. Therefore, it is possible to retain the third part  206 , the fourth part  208 , the fifth part  210 , the sixth part  212 , the seventh part  214 , and the eighth part  216 . Hence, the first part  202  and the second part  204  can be replaced with parts that possess a larger arc. 
         [0039]    Providing the customer with an association as expressed can therefore lead to easier choosing of design elements. If circular door frames and eyebrow door frames are associated with different architectural styles, a customer may holistically know that he or she prefers an eyebrow door frame. However, if the customer has a particular affinity for an architectural style that does not incorporate eyebrow door frames, then a customer can become frustrated because he or she does not know the name of the particular style of door frame or the specific architectural style to which the door frame belongs. Hence, organization of stonework into units, such as the door frame of unit  200 , can assist the customer. 
         [0040]      FIGS. 3 and 4  are examples of profiles. Both the first profile  300  and the second profile  400  are horizontal cross-sections of a given part. The dimensions of each profile  300  and  400  are typically measured by three dimensions. The height Y, the upper depth X and the lower depth Z are related to the overall size of the given part  104 . There are profiles that can be utilized in order to provide varying degrees of aesthetic flair. 
         [0041]      FIGS. 5   a - 5   d  are examples of units.  FIG. 5   a  depicts an unfluted Corinthian column, and  FIG. 5   c  depicts an unfluted Doric column. Specifically, the picture of  FIGS. 5   a  and  5   c  only depict the caps of each of the respective columns because the caps are what differentiate the Corinthian column from the Doric column. 
         [0042]      FIGS. 5   b  and  5   d , on the other hand, depict more complex units. Specifically, each of the respective pictures depicts an entryway.  FIG. 5   b  is denoted as a “Castile Aragon II” that is a style of architecture common to the Aragon region of Northeast Spain.  FIG. 5   d  is denoted as “Boxwood Manor” that is a style of architecture more indicative of the Southwest United States. 
         [0043]    Referring to  FIG. 6  of the drawings, the reference numeral  600  generally designates a system for adjusting dimensions of a given unit. The system  600  comprises a client computer  614 , a computer network  612 , a server  610 , an internal computer  608 , a database of units  604 , a calculation unit  606 , and a database of molds  602 . 
         [0044]    For the system to operate, a user has to access the software capable of selecting and adjusting units for a given architectural style. A client computer  614  will generally use web-based applications to access the software. However, the user may not necessarily be required to use web-based applications. Typically, though, a user will access a web page and input the desired data to obtain the desired drawings. 
         [0045]    In order for the access to take place, a plurality of connections should be made. A client computer  614  is coupled to a computer network  612  through a first communication channel  616 . The computer network  612  can be a variety of computer networks including, but not limited to, the Internet. The computer network  612  is then coupled to the server  610  through a second communication channel  618 . The server is coupled to the internal computer  608  through a third communication channel  620 . The internal computer is then coupled to a database of units  604 , a database of molds  602 , and a calculation unit  606  through a fourth communication channel  624 , a fifth communication channel  626 , and a sixth communication channel  622 . 
         [0046]    Referring to  FIGS. 7   a ,  7   b , and  7   c  of the drawings, the reference numeral  700  generally designates a flow chart for adjusting the dimensions of a given unit. 
         [0047]    In order for the user to utilize the system, the user can input initial data to describe both the uses for the drawings and the basic drawing requirements. In step  702 , the user makes a selection that a new drawing is to be created. Then in step  704 , the user can then select the drawing category. The drawing category is typically defined as the purpose for the drawing, such as development or a Job “Blue Dot.” Once the drawing category has been selected, a drawing type image, such as a parts sheet, is selected in step  706 . Then in step  708 , the user then selects the drawing type detail, such as the front elevation. The last portion of initial data is the job number, which is a business specific number to identify the job that is input in step  710 . 
         [0048]    Once a user has input all of the initial data, the data specifics regarding the scale, quantity and type of materials can be input. The user inputs the scale in step  712 . Then in steps  714  and  716 , respectively, the plot size and “blue dot” number are selected. The user can then select the unit mark or identifier and the part mark or identifier in steps  718  and  720 , respectively. Once all of the data regarding the physical features of the unit or part have been input, the drawing is titled, described, remarked and numbered in steps  722 ,  724 ,  726 , and  728 , respectively. These choices allow a user to effectively choose the marking, the scale, and the units or parts for a drawing that is to be rendered. 
         [0049]    After the user has input all of the background data, the user is prompted as to whether the drawing should be auto-generated in step  730 . If the user does not wish to auto-generate a drawing, a Computer Aided Design (CAD) software package is opened with all of the initially inputted data in step  732 . The CAD package can be a variety of software packages, such as AutoCAD®. However, if the user wishes to have an auto-generated drawing, then the user will be further prompted for information. 
         [0050]    If the user wishes to have an auto-generated drawing, there is a prompt to create a part or unit in step  734 . The parts and units nomenclature is the same nomenclature utilized in the organization scheme of  FIG. 1 . In fact, the system  600  of  FIG. 6  is overlaid on the organization scheme of  FIG. 1 . Therefore, a user will likely be more willing to utilize the system  600  of  FIG. 6  because of the simplicity associated with the logical correlations created in the organizational scheme of  FIG. 1 . 
         [0051]    If the user chooses to create a part, then the user is further prompted regarding parts within the organizational scheme of  FIG. 1 . In step  736 , the user is prompted to select a part type, such as column cap, wherein the parts are selected from the database of units/parts  604  of  FIG. 6 . Then the primary view is selected in step  738 . The primary view of a unit is essentially the overall shape of the unit, for example an eyebrow window frame or a squaretop window frame. For example, a top view is a view of a part from above the part looking down. In step  740 , the part modifiers are selected. The modifiers are additional features that can be added to a unit to provide a certain aesthetic style or aesthetic look, such as a sill added to a window frame. Then, the profile of a part is selected in step  742 . The profile is essentially a cross-sectional view of a part, such as the examples depicted in  FIGS. 3 and 4 . However, the profile can be other views, such as a three dimensional carved stone look on a piece of molding. Finally, the orientation is selected in step  744 . The orientation is the specific view of a part from any angle including the primary view. 
         [0052]    Once all of the features of the drawings have been selected, then in step  746 , the drawing is created. The internal computer  608  of  FIG. 6  utilizes the database of unit/parts  604  of  FIG. 6  to determine the known dimensions and characteristics of the desired part selected. The internal computer  608  of  FIG. 6  employs the calculation unit  606  of  FIG. 6  to adjust the dimensions of the part. The calculation unit  606  of  FIG. 6  utilizes a set of parametric equations to adjust the dimensions of the desired part based on the input dimensions. For example, these equations can include the Pythagoreans theorem, involving sums and squares, and trigonometric equations. 
         [0053]    If the user chooses to create a unit, then the user is further prompted regarding units within the organizational scheme of  FIG. 1 . In step  748 , the client is prompted to select a unit type, such as door frame, wherein the units are selected from the database of units/parts  604  of  FIG. 6 . Then the primary view is selected in step  750 . The primary is the generally the core or the most characteristic cross-sectional view of a given unit. For example, a top view is a view of a part from above the part looking down. 
         [0054]    In step  752 , the part modifiers are selected which are potential, additional features of a unit. Then, the generic unit with all parts is displayed, wherein the parts are labeled with the standardized alpha-numeric identification strings in step  754 . Once displayed, the profile family of a unit is selected in step  756 . The profile is generally a cross-sectional view of a part, such as the examples depicted in  FIGS. 3 and 4 . In the case of a unit, a family of profiles is selected because each part contained within a given unit has a specific profile. Also, the profiles within a given unit may vary slightly or drastically. Finally, the profile offsets are displayed in step  744 . 
         [0055]    After the profile offsets have been displayed, the user is prompted as to whether a previous profile is to be utilized in step  758 . If a previous profile is selected, then a new or previous offset is selected in step  770 . However, if a previous profile is not selected, then a new profile is selected and displayed in steps  772  and  774 , respectively, and new offsets are chosen in step  776 . After the respective profiles and offsets have been chosen, then the profile interface drawing is created in step  778 , and the settings are saved in step  780 . 
         [0056]    Once all of the features of the drawings have been selected, then in step  782 , the drawing is created. The internal computer  608  of  FIG. 6  utilizes the database of unit/parts  604  of  FIG. 6  to determine the known dimensions and characteristics of the desired unit selected. The internal computer  608  of  FIG. 6  employs the calculation unit  606  of  FIG. 6  to adjust the dimensions of each part of the unit. The calculation unit  606  of  FIG. 6  utilizes a set of parametric equations to adjust the dimensions of each part of the unit based on the input dimensions. Also, if the mortar joint dimensions have changed then the figure is redrawn in step  784 . 
         [0057]    In order to implement the process of selecting the desired units with the desired dimensions, a computer program is employed. The computer program typically utilizes a plurality of menus. The menus provide a graphical interface to a user that is more user friendly. Organization of the menu selections mirrors the procedure depicted in  FIGS. 7   a ,  7   b , and  7   c . However, a plurality of text command prompts, similar to those utilized is such programs as Simulation Program with Integrated Circuit Emphasis (SPICE) can also be employed. 
         [0058]    Referring to  FIG. 8  of the drawings, the reference numeral  800  generally designates a block diagram depicting a unit generation menu. The menu  800  comprises a menu label  802 , a first pull-down selection window  806 , a second pull-down selection window  808 , a third pull-down selection window  810 , a thumbnail window  804 , and a thumbnail image  812 . 
         [0059]    The menu operates by allowing the user to select a desired unit, such as a window frame. The menu label  802  is typically located at the top of the menu to provide guidance to a user so as to better prevent confusion. The first pull-down selection window  806  is to allow the user to select the desired unit. The first pull-down selection window  806  contains a complete list of units that the manufacturer provides. The second pull-down selection window  808  is the primary view of the unit selected in the first pull-down selection  806 . The primary view generally depicts the overall shape of the unit. In the menu  800 , a surroundwindow has been selected as the unit and the primary view is a square top. The selection of a squaretop is the shape of the window frame as opposed to an eyebrowtop, which is a more curved shape. 
         [0060]    In addition to selecting both the unit and the primary view, a modifier can be selected. The modifiers are any additional options that can be added to a unit. The selection of the modifier is made as a result of utilizing the third pull-down selection window  810 . The modifiers are items that can be added to a unit to provide differing styles or looks. For example, the menu  800  has a selection of a sill. The sill is the bottom portion of the window that provides additional styles. Furthermore, there can be multiple pull-down selection windows or a single pull-down selection window, as shown in  FIG. 8 , for each of the pull-down selection windows. 
         [0061]    Also included in the menu  800  is a picture window. Contained within the picture window is a picture of the selected unit with all of the included features. As a selection is made, be it a unit, a primary view, or a modifier, the picture is updated. The advantage to having a continually updating picture is to provide real-time feedback to a user. The user, then, can properly select his or her desired features in an efficient manner. 
         [0062]    Referring to  FIG. 9  of the drawings, the reference numeral  900  generally designates a block diagram depicting a dimension input menu. The control menu  900  comprises a unit picture  908 , a menu label  902 , a first control dimension input  904 , and a second control dimension input  906 . 
         [0063]    The menu operates by allowing the user to input the desired dimensions of a unit, such as a window frame. The menu label  902  is typically located at the top of the menu to provide guidance to a user so as to better prevent confusion. The first control dimension input  904  and the second input dimension input  906  allow the user to enter n the dimension of the unit. There can be a single dimension or multiple dimensions, as shown in  FIG. 9 . There can also be a number of additional dimensions, such as radius, that can be unit specific. Moreover, there are a number of measurement units that can be utilized as input dimensions, such as English, Meter-Kilogram-Second (MKS), Centimeter-Gram-Second (CGS), and so forth. 
         [0064]    Entering a measurement unit into a computer does not necessarily assist a user in attaining his or her desired dimensions. As a matter of fact, it may be difficult to ascertain which dimension each of the inputs refers to. The unit picture  908 , though, provides all of the necessary detail for the user to have a firm understanding of the correlation between the respective control dimensions and the physical measurements of the unit. As an example in  FIG. 9 , the first control input dimension  904  corresponds to the inner height of the window frame depicted by the unit picture  904 , and the second control input dimension  906  corresponds to the inner width of the window frame depicted by the unit picture  904 . Therefore, a user is able to visualize a unit, which is composed of manufactured stone, complete with actual physical dimensions, wherein the physical dimensions are calculated through the use of a plurality of parametric equations. 
         [0065]    Referring to  FIG. 10  of the drawings, the reference numeral  1000  generally designates a block diagram depicting a profile/family selector menu. The profile menu  1000  comprises a menu label  1002 , a unit picture  1012 , a first profile selection window  1006 , a second profile selection window  1008 , a first image thumbnail  1004 , a second image thumbnail  1010 , and a unit label  1014 . 
         [0066]    The menu operates by allowing the user to input the desired unit profile, such as a window frame. The menu label  1002  is typically located at the top of the menu to provide guidance to a user so as to better prevent confusion. Essentially, usually the profiles are horizontal cross-sectional views of various parts that make up the unit. However, a profile can also be of a variety of other types of profiles such as an overall view of a plurality of three dimensional leaves that appear as a molding. With each selection window there is an associated image thumbnail to depict the shape of the profile to a user. In  FIG. 10 , the first profile selection window  1006  is associated with the first thumbnail image  1004 , and the second profile selection window  1008  is associated with the second thumbnail image  1010 . Also, a unit label  1014  is provided. The unit label  1014  can display specific unit nomenclature, such as Surroundwindow Squaretop Sill as shown in  FIG. 10 . 
         [0067]    Typically, the number of image thumbnails and selection profiles corresponds to the number of selectable profiles of a unit. For example, the window frame of  FIG. 10  has two sections where the profile can be different. It is possible to have a system where a profile for each individual part of a unit is selectable. However, according to the majority of aesthetic conventions, certain portions, such as the top three parts of the window frame of  FIG. 10 , have the same profile. Hence, for the sake of simplicity, certain parts of units are presumed to have a uniform profile so as to not overload a user with too many possible selections. 
         [0068]    In the window of  FIG. 10 , certain aesthetic conventions have been adhered to so a user can select the desired profiles. Accordingly, the user is prompted to select a profile for the top three parts of the window frame from the first profile selection window  1006 , and the user is prompted to select a profile for the sill of the window frame from the second profile selection window  1008 . Once each of the respective profiles has been selected, then a thumbnail image of the selected profile for each of the top three parts of the window frame appears as the first image thumbnail  1004 , and a thumbnail image of the selected profile for the sill of the window frame appears as the second image thumbnail  1010 . Therefore, a user can mix and match varying profiles of portions of the unit to attain a desire aesthetic look in real-time for the stonework. 
         [0069]    Referring to  FIG. 11  of the drawings, the reference numeral  1100  generally designates a block diagram depicting a link menu. The link menu  1100  comprises a menu label  1102 , a unit picture  1104 , a first selection slot  1106 , a second selection slot  1108 , a third selection slot  1110 , a fourth selection slot  1112 , a fifth selection slot  1114 , a sixth selection slot  1116 , a seventh selection slot  1118 , an eighth selection slot  1120 , and a ninth selection slot  1122 . 
         [0070]    The menu operates by allowing the user to input the desired unit additions, such as a window sill. The menu label  1102  is typically located at the top of the menu to provide guidance to a user so as to better prevent confusion. Overall, though, the link menu is typically associated and selected from the profile menu  1000  of  FIG. 10 . There can be other features that can be added to a given unit that are characteristically more like a profile, such as a key. These other features are selected at the same time or near the same time that a profile is selected due to that logical association. 
         [0071]    In the example in  FIG. 11 , features are added to the window frame. Each of the selection slots, though, corresponds to a different feature of the window. The first slot  1106  is associated with the main surround. The second slot  1108  is associated with a crown. The third slot  1110  is associated with an ear. The fourth slot  1112  is associated with a key. The fifth slot  1114  is associated with the sill. The sixth slot  1116 , the seventh slot  1118 , the eighth slot  1120 , and the ninth slot  1122  are each left blank. The user in the link menu  1100  can select all of the features normally associated with the selected unit. It is possible to have a virtually infinite number of additional features that can be added to any given unit; however, the additional features that can be selected in the link menu  1100  are associated with typical aesthetic conventions. 
         [0072]    Referring to  FIG. 12  of the drawings, the reference numeral  1200  generally designates a block diagram depicting a first structure/profile interface menu. The first interface menu  1200  comprises a menu label  1202 , a first selected profile  1204 , a second selected profile  1206 , default back  1208 , an offset back  1210 , an offset choice slot  1216 , and a error point  1214 . 
         [0073]    The menu operates by allowing the user to input the desired adjustments for unit profiles. The menu label  1202  is typically located at the top of the menu to provide guidance to a user so as to better prevent confusion. In the first profile selection menu  1200 , each of the previously selected profiles is displayed. For example, with the window frame, there are two choices for profiles: a profile for the main surround and a profile for the sill. The first profile  1204  corresponds to the profile for the main surround, and the second profile  1206  corresponds to the profile for the sill. 
         [0074]    With each profile, there is a default backing  1208 . The default backing is the default mounting line where the part is adjacent to a wall or other rigid structure. The only exception to having a default backing is a cap. When a default backing exists, though, the default backing  1208  refers to the resting location for the part possessing the profile. However, to provide maximum flexibility, the user is given the option to choose an offset. The offset is entered in the offset choice slot  1216  and is illustrated by the offset back  1210 . 
         [0075]    There are cases, though, where the offset can be too large. If the offset is too large, features of the profile can be disturbed or destroyed. For example, the profile of the sill for the window illustrated by the second profile  1206  may lose a portion of the feature associated with the profile because the offset is too large. The error point  1214  is a measurement of when features of a profile may be disturbed or destroyed. If a calculation is made that a feature of a profile may be disturbed or destroyed, then the user can be alerted of the possible ramifications of the choice of such a large offset. Also, there are a number of measurement units that can be utilized as amounts for an offset, such as English, MKS, CGS, and so forth. 
         [0076]    Referring to  FIG. 13  of the drawings, the reference numeral  1300  generally designates a block diagram depicting a first structure/profile interface menu. The second interface menu  1302  comprises a menu label  1302 , a first selected profile  1304 , a second selected profile  1306 , default back  1308 , a user-defined offset  1310 , a first prompt  1314 , a second prompt  1316 , a third prompt  1318 , a fourth prompt  1320 , fifth prompt  1322 , and a sixth prompt  1324 . 
         [0077]    The menu operates by allowing the user to input the desired adjustment for unit profiles. The menu label  1302  is typically located at the top of the menu to provide guidance to a user so as to better prevent confusion. Again with the second profile selection menu  1300 , each of the previously selected profiles is displayed. For example, with the window frame, there are two choices for profiles: a profile for the main surround and a profile for the sill. The first profile  1304  corresponds to the profile for the main surround, and the second profile  1306  corresponds to the profile for the sill. 
         [0078]    With each profile, there is a default backing  1308  and a user-defined offset  1310 . However, to provide maximum flexibility, the profile can also be moved. The user is prompted by the first prompt  1314  to move the first profile  1304  and by the fourth prompt  1320  to move the second profile  1306 . If a desires to move either of the respective profiles, then the user can enter whether the profile is to be moved in a positive or negative direction. The second prompt  1316  corresponds to the direction of motion of the first profile  1304 , and the fifth prompt  1322  corresponds to the direction of motion of the second profile  1306 . Once the direction of motion of the profile is entered by the user, then the user can enter the amount. The third prompt  1318  corresponds to the distance of motion of the first profile  1304 , and the sixth prompt  1324  corresponds to the distance of motion of the second profile  1306 . Also, there are a number of unit measurement that can be utilized as amounts for an offset, such as English, MKS, CGS, and so forth. 
         [0079]    Referring to  FIG. 14  of the drawings, the reference numeral  1400  generally designates a block diagram depicting a parts interface menu. The parts interface menu  1400  comprises a menu label  1402 , a first sill view  1404 , a second sill view  1406 , a first surround intersection  1410 , a second surround intersection  1414 , a third surround intersection  1420 , a fourth surround intersection  1424 , a predefined dimension  1412 , a first outer surround boundary  1408 , a second outer surround boundary  1416 , a third outer surround boundary  1418 , a fourth outer surround boundary  1420 , an offset prompt  1428 , and an offset  1422 . 
         [0080]    The menu operates by allowing, the user to input the desired adjustments to the unit dimensions. The menu label  1402  is typically located at the top of the menu to provide guidance to a user so as to better prevent confusion. The first sill  1404  is the default view. The first outer surround boundary  1408  and the second outer surround boundary  1416  match the outer edges of the sill while the predefined dimension  1412  is maintained. The first surround intersection  1410  and second surround intersection  1414  can be seen on the surface of the sill, which depicts the location of the surround relative to the sill. This type of view and menu are typically available for any situation where there can be an adjustment between parts, such as between a unit and a modifier like the window frame and sill. 
         [0081]    To provide maximum flexibility to a user to choose the aesthetic style, the dimensions of the sill, or other parts, can be adjusted relative to the surround, or other units. The first sill  1404  is the adjusted view. The third outer surround boundary  1418  and the fourth outer surround boundary  1426  do not necessarily match the outer edges of the sill; however, the predefined dimension  1412  is maintained. The third surround intersection  1420  and fourth surround intersection  1424  can be seen on the surface of the sill, which depicts the location of the surround relative to the sill. The customer can enter an offset  1422  into the offset prompt  1428 . The offset  1422  in the context of the window frame is defined as the linear distance between the respective outer surround boundary and the edge of the sill; however, the offsets can vary in definition according to the respective usage. It would be more flexible for a user to be able to adjust every distance, but according to normal aesthetic conventions, symmetry is preferred. Also, there are a number of measurement units that can be utilized as amounts for an offset, such as English, MKS, CGS, and so forth. 
         [0082]    Referring to  FIG. 15  of the drawings, the reference numeral  1500  generally designates a block diagram depicting a CAD drawing. The CAD drawing  1500  comprises a vertical cross-sectional view  1502 , a cap horizontal cross-section  1504 , and a base horizontal cross section  1506 . 
         [0083]    The CAD drawing depicts a Corinthian column. The vertical cross-sectional view  1502  is typically considered to be the primary view of the column as it would stand in a building. The drawing  1500 , though, is scaled and complete with dimensions (not labeled). Specifically, though, vertical cross section  1502  illustrates both height and width of the column. 
         [0084]    However, in order to yield a complete perspective of the overall shape of the column other perspectives or views are included. The cap horizontal cross-section  1504  and the base horizontal cross section  1506  provide the other perspective views. These other views allow for complete consideration of scale. By examining the dimensions of the cap horizontal cross-section  1504  and the base horizontal cross section  1506 , taper and the respective radii can be determined, giving a user an overall complete view of the unit to be built. An example of an embodiment of the invention is further described in Appendices A to M, the contents of which are hereby incorporated by reference. 
         [0085]    By providing easily usable software to enable either a laymen or more sophisticated professional to choose custom stonework, the economic benefits are substantial. The systems and software allow a user to use graphical interfaces to easily select entire units, like window frames, that are to be custom made of manufactured stone. A user can vary the sizes and styles to fit his or her liking, while eliminating costly procedures involving various craftsmen, such as draftsmen. A computer generates the drawings to scale for the custom stonework that allows a manufacturer to produce the parts of a unit at a greatly reduced cost to a user or consumer. Moreover, the use of a more simplistic, user friendly software package reduces the gargantuan task of designing and producing scaled drawings for manufacturing to a rapid and simple process.
