Conversion from BREP to CATProduct is not supported yet :(

A Brep file is a 3D model stored in the boundary representation (also known as B-rep). The Brep format is a part of Open CASCADE Technology (OCCT).

The Brep structure is made up of two major components:

• topological components such as faces, vertices, and edges;
• links between components such as surfaces, points, and curves.

It comprises three-dimensional data such as vertices, edges, wires, faces, shells, solids, compounds, edge and face triangulations, polylines on triangulations, space location, and orientation.

The CATProduct file format is associated with CATIA V5 assembly format and is used to simulate industrial design processes.

Unlike CATPart files, CATProduct does not contain any geometric information, only model parts, and assembly structure information. Nevertheless, single CATPart files can be generated from CATProduct assembly.

The CATPart extension is compatible with Autodesk Inventor / Fusion 360, and Okino Computer PolyTrans software.
