This part of ISO 10303 specifies the interpretation of the integrated resources to satisfy requirements for the

representation of the product shape using geometrically bounded wireframe models.

The following are within the scope of this part of ISO 10303:

— points and curve geometry in 3D cartesian space;

— the use of wireframe geometry to represent a shape;

— the combination of representations to form an aggregation of representations.

The following are outside the scope of this part of ISO 10303:

— surface geometry;

— topological connectivity of geometry;

— product definitions.
