ISO 10303-501:2000 PDF

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 that are bounded by a set of

connected edge sets.

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 connected edge sets 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;

— shell topology.
