The B-rep used by HOOPS Exchange may not be completely compatible with modeling systems that do not support the full range of B-rep as employed by PRC. A3DCopyAndAdaptBrepModel attempts to convert PRC B-rep into a format that is compatible with your system.

This program demonstrates how to programmatically adapt B-rep models to your particular needs using HOOPS Exchange. B-rep
is always found in this hierarchy:

Model file > Product occurrence > Part definition > B-rep

The functions below attempt to find the B-rep entities by traversing the model tree.

This program reads a model file and outputs a PRC file. Specify these files on the command line (see 'Usage').

- Load a CAD file
- Traverse the entire data structure
- Call A3DCopyAndAdaptBrepModel for each BrepModels.
- Copy inputs BrepModels.
- Selected Geometricals surfaces are converted to nurbs.
- Faces are split.
- UV Curves are computed.
- New modified data are populated
- PRC is exported from the modified data
