36、ation about shape - such as tolerances or surface finish - which constrains the results of a manufacturing process, but does not specify the process itself. It may include a record of the geometrical operations, such as trimming a surface, which allow the shape to be subsequently edited, but exclude
37、s parametric design, in which shapes are generated using specific knowledge embedded in the CAD software 3.2 CAD 3D geometry the representation of the geometric aspects of the part or assembly, using concepts such as point, line, cube, etc. Note 1 to entry: For more information: see Annex B.

CAD 3D topology
39、covers the system of relationships needed to interpret a collection of lower dimensional geometric elements as a 3D volume Note 1 to entry: For more information: see Annex B. 3.4 “explicit” representation of a CAD model in the context of engineering and 3D geometrical the term explicit representatio
40、n refers to the mathematical representation of the final result of the CAD model., From the designers point of view, it corresponds to the 3D shape (points, curves, surfaces, solids), together with Geometric Dimensions and Tolerancing Note 1 to entry: Explicit 3D shape may be associated with non-geo
41、metric data including design management meta-data such as layer, colour or group or user defined properties. These non-geometric data are optional, and are added by users and checked and validated by specific tools. 3.5 “implicit” representation of a CAD model CAD model uses an implicit representati
42、on if its geometrical representation is based on a parameterization (e.g. 2D parametric sketches, 3D parametric features such as extrusions of 2D sketches, holes, pockets), together with a set of operations (e.g. extrusion, revolution) or constraints (e.g. perpendicularity, parallelism) Note 1 to en
43、try: The result of the processing of an implicit representation is a CAD 3D explicit representation, which can be used then for geometric operations such as measurement or clash detection. 3.6 3D Geometric Dimensioning 3D geometric dimensioning; 3D geometric tolerances. Note 2 to entry: Dimensioning
44、 information is required to define the characteristics of the 3D explicit model, e.g. in terms of length or height. This additional information may be linked to one geometrical characteristic, e.g. the length of a line. Note 3 to entry: No design geometrical feature can be manufactured to perfection
45、, so the feature description can be extended with tolerance information. Tolerances may come in the form of limits of size applied to given dimensions, with null style tolerance applied directly to dimensions or constraints, such as flatness or parallelism, or a general note.

48、ric shape; the presentation of that formula for a geometric display requires that the representation is rendered by the corresponding shape; the process of rendering requires additional presentation information, such as colour or transparency Note 1 to entry: For example, a curve may be displayed as
49、 a set of pixels of a particular colour in a computer screen. For example, 3D Geometric Dimensioning and Tolerancing may be presented as a set of 3D polylines, however, if the GD Annex B: overview of the main types of CAD 3D mechanical information; Annex C: overview of the main CAD mechanical assembly structure information; Annex E: considerations for long term preservation of CAD 3D information.
