What is a CATPART file

CATPART files mostly belong to CATIA by Dassault Systèmes. CATPART is the filename extension of a 3D mechanical product part's description created with CATIA Computer Aided Design (CAD), Computer Aided Engineering (CAE), and Computer Aided Manufacturing (CAM) software suite. Contents of the file include 3D geometry, dimensions, and metadata which make up the 3D model of a part. Multiple CATPART files are combined into a single CATPRODUCT assembly file which is the whole product model.

How to open a CATPART file

You need a suitable software like CATIA from Dassault Systèmes to open a CATPART file.
