适用范围：This part of ISO 10303 specifies the interpretation of the integrated resources in order to satisfy require-ments for the representation of geometric shapes by means of geometrically bounded surface models. The following are within the scope of this part of ISO 10303: — 3D points; — points defined in the parameter space of curves or surfaces; — 3D curves; — curves defined in the parameter space of surfaces; NOTE - Such curves are also known as pcurves or cons, which are acronyms for parametrised curve and curve on surface. — the elementary curves line, circle, ellipse, parabola, and hyperbola; — intersection curves; — polylines that consist of at least three points; — surfaces; — the elementary surfaces plane, cylinder, cone, torus, and sphere; — swept surfaces created by rotation or linear extrusion of a curve; — sculptured curves and surfaces; — trimming of curves and surfaces; — composition of curves and surfaces; — replication of curves, surfaces, and surface models; — 3D offsets of curves and surfaces. The following are outside the scope of this part of ISO 10303: — unbounded geometry; — self-intersecting geometry; — geometry in a 2D cartesian coordinate space; — replication of points; — topological entities.
