How to convert CATIA (.catpart,.catproduct) to 3MF?

PolyTrans|CAD+DCC performs mathematically precise CAD, DCC/Animation, GIS and BIM 3D file conversions into all key downstream 3D packages and file formats. Okino software is used and trusted throughout the world by many tens of thousands of 3D professionals in mission & production critical environments, backed by respectable personal support directly from our core development team.



CATIA, developed by Dassault Systèmes, is an integrated suite of CAD, CAE and CAM applications for digital product definition and simulation. CATIA is primarily used by the automotive and aerospace industries for automobile and aircraft product and tooling design.

The key file extensions used with CATIA v5 software are ".catpart" for the part and geometry files, and ".catproduct" for the assembly files.

Conversions from CATIA can best be done either via Okino's native CATIA v5 importer (which is based on the real and actual CATIA v5 runtime system licensed from Dassault Systèmes), or equally well via STEP AP214 files.



3MF, 3D Manufacturing Format, is a modern replacement for the legacy STL (StereoLithography) file format with an explicit focus on the proper transmission of CAD and non-CAD model data for 3D printing as well as to downstream services and platforms. From Okino's long term perspective, the VRML2 file format was and is "just as good" for such requirements but never had the correct understanding nor traction since its introduction in 1995.

Features of 3MF over the legacy STL format includes: geometry instancing support, layered texture maps, multiple layers of UV texture coordinates, vertex colors and extended material types.

History, features, overviews, implementation partners and more can be read on the 3MF Consortium’s web site.

Note: Microsoft Windows uses the 3D Manufacturing Format (.3mf) for all 3D printing tasks.
