ISO 10303-501:2000

Industrial automation systems and integration — Product data representation and exchange — Part 501: Application interpreted construct: Edge based wireframe

Scope

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.
