ISO 10303-502:2000 PDF Download

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.
