Structure Module
################

Creates and accesses structural PRC entities.

This module describes the functions and structures that allow you to create and parse PRC structure entities. PRC structure entities have names of the form ``A3DAsmEntity_name``\ , for example :c:type:`~A3DAsmProductOccurrence`\ .

The PRC structure entities can be adapted to support a variety of 3D modelling formats, including specific CAD formats, neutral 3D formats such as IGS, and tessellation formats such as VRML.
