Conversion from CATProduct to PRT is not supported yet :(

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.

A PRT format is used to store components of 3D CAD models. It may contain lines, surfaces, textures, dimensions, and metadata.

The .prt extension is mostly associated with the Siemens NX Part (PRT) file type as an acronym for "part". PRT files may be exported to various standard CAD and 3D modeling formats (e.g. OBJ and STL) in addition to being utilized natively in Siemens NX.

The PRT file is also a part created by PTC Creo Parametric 3D software. In PTC Creo, project part files can be combined in a single assembly file with an ASM extension.

Despite the same extension name different CAD software produce PRT files differently, i.e. PRT files produced with Creo are not the same as PRT files generated from NX.

The PRT extension is also compatible with Dassault Systèmes SOLIDWORKS.
