Conversion from CATProduct to CATIA V6 (3D XML) 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.

3DXML is an open-standard proprietary 3D file format developed and supported by Dassault Systemes. 3DXML files are typically created as exports from Dassault Systemes' 3DEXPERIENCE application. The 3DXML file is a zip archive file consisting of a BOM file and one or more 3D representations stored in either XML or binary format. Compact file size allows users to transfer 3D XML quickly and embed it into websites, emails, and various MS Office documents. Therefore, the format is commonly used to integrate 3D data into technical documentation.
