Application module: Edge based wireframe

1 Scope

This part of ISO 10303 specifies the application module Edge based wireframe. 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;
• the representation of points defined in a three-dimensional coordinate space;
• the representation of curves, including b-splines, defined in a three-dimensional coordinate space;
• the representation of a single wireframe model or an assembly of wireframe model.

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.
