How to convert CATIA (.catpart,.catproduct) to glTF?

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

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.

glTF

As described more extensively on Okino's dedicated glTF converter page, glTF is a newer 3D file format designed for the "last mile" of efficient, real-time delivery of 3D assets for Web-based browsers, AR/VR applications and gaming applications, amongst others. It is generally not to be considered as a long term and high fidelity 3D data storage format (such as FBX, COLLADA or VRML2) but rather an efficient transmission and viewing 3D file format. It has begun to gain good traction in recent years.

glTF stands for Graphics Language Transmission Format. glTF is intended as a vendor-neutral distribution format for 3D content, bridging the gap between 3D content creation tools and applications displaying 3D graphics. It is fully graphics API and operating system-independent.

Okino has one of the most extensively developed and refined implementations of glTF for both import and export.
