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.
