适用范围：This part of ISO 10303 specifies the interpretation of the generic resources for the definition of an ele-mentary boundary representation model. The following are within the scope of this part of ISO 10303: — the definition of an elementary_brep_shape_representation, this is a representation composed of one or more manifold_solid_breps each of which is defined with elementary geometry and complete explicit topology; — the definition of the unbounded geometry of curves and surfaces used in the definition of the faces of such a B-rep model; — the definition of the topological structure of a B-rep model; — 3D geometry; — B-reps; — elementary curves, these are lines or conies; — elementary _surfaces; — geometric transformations; — polylines; — unbounded geometry; — use of topology to bound geometric entities. The following are outside the scope of this part of ISO 10303: — 2D geometry; — bounded curves other than polylines; — bounded surfaces; — offset curves and surfaces. This AIC is independent of any industrial application domain.
