Conversion from BREP to ASM 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.

ASM (Solid Edge Assembly) is one of the data file types used by Solid Edge CAD software. The files with .asm extension contain 3D parts (.prt) which consist of assemblies. ASM by itself, does not contain geometric information – it stores only the rules for connecting parts.

ASM (Solid Edge Assembly) also has no connection with assembly language, though this also uses an .asm extension.

Among CAD applications that support ASM extension are PTC Creo and Autodesk Fusion 360.
