适用范围：This part of ISO 10303 specifies the interpretation of the integrated resources to satisfy requirements for the representation of the product shape using three-dimensional wireframe models which are bounded by a set of shells. The following are within the scope of this part of ISO 10303: — the representation of wireframe models that are described by a graph of edges and vertices where the edges intersect only at their vertices; — the representation of a wireframe model by one or more shells that shall not overlap or intersect except at their vertices or edges; — points defined in a three-dimensional coordinate space; — curves, including b-splines, defined in a three-dimensional coordinate space; — the representation of a single wireframe model or an assembly of wireframe models. The following are outside the scope of this part of ISO 10303: — geometry defined in a two-dimensional coordinate space; — surface geometry; — solid geometry; — references to eliminated constructs.
