2 Page 2 Provläsningsexemplar / Preview Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO was prepared by Technical Committee ISO/TC 10, Technical drawings, product definition and related documentation, Subcommittee SC 8, Construction documentation. ISO consists of the following parts, under the general title Technical product documentation Organization and naming of layers for CAD: Part 1: Overview and principles Part 2: Concepts, format and codes used in construction documentation Part 3: [under study] Annex A of this part of ISO is for information only.
3 Provläsningsexemplar / Preview Sida 2 Förord ISO (den Internationella Standardiseringsorganisationen) är en världsomspännande sammanslutning av nationella standardiseringsorgan (ISO-medlemmar). Internationella standarder utarbetas vanligen i ISO:s tekniska kommittéer. Varje medlemsland, som är intresserat av det arbete som pågår i någon teknisk kommitté, har rätt att bli medlem i denna. Internationella organisationer, myndigheter och privata, som samarbetar med ISO, deltar också i arbetet. ISO har nära samarbete med Internationella Elektrotekniska Kommissionen (IEC) i alla frågor som berör elektroteknisk standardisering. Förslag till internationella standarder som godkänns av de tekniska kommittéerna sänds till medlemsländerna för röstning. För att publiceras som internationell standard krävs att minst 75% av de medlemmar som röstar godkänner förslaget. Den internationella standarden ISO har utarbetats av den tekniska kommittén ISO/TC 10, Technical drawings, product definition and related documentation, underkommitté SC 8, Construction documentation. ISO består av följande delar med den gemensamma titeln Teknisk produktdokumentation Organisation och benämning av CAD-lager: Del 1: Översikt och principer Del 2: Begrepp, format och koder för användning i byggdokumentation Del 3: Tillämpning av ISO och ISO Bilaga A i denna del av ISO är endast informativ.
4 Page 3 Provläsningsexemplar / Preview Introduction ISO consists of three parts which deal with CAD layer organization and naming. ISO has a general application whereas ISO and ISO/TR are applicable to construction projects. The purpose of ISO is to establish a common international basis for organizing data in CAD systems that covers the structuring of data into layers.
5 Provläsningsexemplar / Preview Sida 3 Orientering ISO består av tre delar, vilka behandlar organisation och benämning av CADlager. ISO behandlar den allmänna tillämpningen medan ISO och ISO/TR är tillämpliga på bygg- och anläggningsprojekt. Syftet med ISO är att fastställa en gemensam internationell grund för att organisera de data i CAD-system som täcker strukturering av data i CAD-lager.
6 Page 4 Provläsningsexemplar / Preview Technical product documentation Organization and naming of layers for CAD Part 1: Overview and principles 1 Scope This part of ISO establishes the general principles of layer structuring within CAD files. Layers are used to control visibility and to manage and communicate CAD file data. Layer names are used to represent this structure. The principles are applicable to all parties involved in preparing and using technical documentation on computer systems. Although these principles are primarily for users, CAD system developers are expected to provide software tools capable of implementing and supporting this part of ISO An important use is also to structure data in component libraries produced by third parties. 2 Normative reference The following standard contain provisions which, through reference in this text, constitute provisions of this part of ISO At the time of publication, the edition indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO :1994, Industrial automation systems and integration Product data representation and exchange Part 201: Application protocol: Explicit draughting. 3 Definitions For the purposes of this part of ISO 13567, the definitions for CAD draughting given in ISO and the following definitions apply. 3.1 layer: Organizational attribute of entities in a CAD data file, used to separate data in order to manage and communicate those data and to control visibility on the computer screen and on plotted drawings. NOTE In CAD systems, synonyms for "layer" are used, for example "level". 3.2 CAD model: Structured CAD data file(s) organized according to the physical parts of the objects represented, for example a building or a mechanical device. NOTE Models can be two-dimensional or three-dimensional, and can include graphical as well as non-graphical data attached to the objects.
