Scope

This International Standard specifies the required scope and use of information requirements for integrated resources used to display drawings. NOTE: The Application Activity Model (AAM) in Annex F provides a graphical representation of the processes and information flows that are the basis for defining the scope of this standard. This International Standard may be used for the intra-organizational exchange of computer-interpretable graphical information and product definition data. The following are within the scope of this standard: - the representation of drawings for the purpose of exchange, especially for applications in mechanical engineering, architectural engineering and structures; The application and use of geometric equivalence; Example: the expression of the product shape by the receiving system requires not only the support of visible equivalence graphics exchange, but also the support of real geometric equivalence. These uses include the calculation of distance or area, and the calculation of CNC tool paths generate. -- a graphical representation describing a certain design stage; -- a representation of the modification of a single drawing; -- a representation of a two-dimensional cartographic shape model describing product shape and view-generating transformations; Representation of shape product definition data; -- Hierarchy of diagrams, sheets and views of cartographic shape models; -- Mechanisms for describing element combinations on diagrams; -- Management data for diagram management; -- Identification of information provided by diagrams Management data for the product version. The following content is not within the scope of this standard: - expression of product shape using three-dimensional geometry; - expression of product shape not described in the drawing; - expression of drawing not related to the product; - exchange of drawing origin; -- the definition of annotations in the three-dimensional coordinate system; -- the representation of dimensions and annotations related to the view geometry and annotations; -- the material structure sheets interpretable by the computer other than those conveyed by annotations on the drawings ; -- Strict implementation of cartographic standards; -- Diagrams containing non-displayable attribute data (not required to manage the data); Example: Non-displayable attribute data can be density, mass, or moments of inertia. -- Automatic generation of diagrams including views, dimensions and annotations. -- Data exchange for drawing or hard copy versions of established diagrams only. Example: Printer or plotter data could be a pen ID, plot scale, or plot color specification
