Conversion from KOMPAS-3D to CATPart is not supported yet :(

KOMPAS-3D is a flexible 3D modeling system that allows creating models by several methods, including the following ones:

Bottom-up modeling using finished components. Top-down modeling by designing components to match specific designs. Modeling based on layout drawings, such as kinematic diagrams. Or any combination of these modeling methods. These approaches allow creating editable associative models easily.

The KOMPAS-3D system has powerful functions for managing projects of thousands of sub-assemblies, parts, and standard library products. It supports all the capabilities of 3D solids and surface modeling that have become the standard among medium-level CAD/CAM programs.

CATPart is a native format developed by Dassault Systems for storing parts of the assemblies created in CATIA V5 software suite, which is extensively used in mechanical engineering including aerospace, automotive, shipbuilding and other domains.

CATPart stores geometry, structure and metadata of 3D models dedicated to single parts. Multiple CATPART files can be combined into a CATProduct assembly file.

Among CAD applications that support CATPart extension are Autodesk Inventor, Fusion 360, and 3ds Max.
