Scope

The application interpreted construct defined in this part specifies the interpretation of the generic resources in order to satisfy the following requirements: — For the definition of an advanced boundary representation model. An advanced B-rep model is a representation composed of one or more manifold_solid_breps each of which is defined with elementary geometry or sculptured geometry. — For the definition of the unbounded geometry of curves and surfaces used in the definition of the faces of such a B-rep model. — For the definition of the topological structure of a B-rep model. In particular all surfaces are bounded by defining an associated advanced-face and all curves are bounded by reference from a topological edge_curve. This AIC is independent of any industrial application domain. The following are within the scope of this part of ISO 10303: — 3D geometry; — B-reps; — B-rep models; — B-spline curves and surfaces; — conies; — elementary curves; — elementary surfaces; — geometric transformations; — polylines; — pcurves; — sculptured surfaces; — surface curves; — swept surfaces; — twisted curves; — unbounded geometry; — use of topology to bound geometric entities. The following are outside the scope of this part of ISO 10303: — 2D geometry other than for the definition of a pcurve in the parameter space of a surface; — bounded curves other than polylines and B-spline curves; — bounded surfaces other than B-spline surfaces; — offset curves and surfaces.
