Geometric Modeling Script Functions

This chapter explains script functions that can be used in shape scripts to build 3D models used in GDL files.

3D models built by these script functions are either surfaces consisting of a set of planar faces or volumes bounded by a set of planar faces.

In a closed volume boundaries of faces must be traversed in counter clock wise direction as seen from the tip of the plane normal pointing out of the volume.

Typically shape scripts first define the geometry (enter coordinates for points) and then create faces and specify which points make each face.
