Application module: Shell based wireframe

1 Scope

This part of ISO 10303 specifies the application module Shell based wireframe. The following are within the scope of this part of ISO 10303:

• representation of wireframe models that are described by a graph of edges and vertices where the edges intersect only at their vertices;
• representation of a wireframe model by one or more shells that shall not overlap or intersect except at their vertices or edges;
• representation of points defined in a three-dimensional coordinate space;
• representation of curves, including b-splines, defined in a three-dimensional coordinate space;
• 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.
