CATPART File Extension

What is CATPART file?

Files with .CATPART extension contain 3D CAD/CAM/CAE model parts and structured data associated with them. CATPART files are saved in a proprietary format developed by CATIA. CATPART files constitute a larger project or a functional element of such project created using CATIA V5. CATIA assembly files use .CATPRODUCT extension.

Uses of CATPART files

CATPART files can store various engineering projects. CATPART files can contain functional elements of projects in such areas as:

• Building and infrastructure development,
• Product design,
• Mechanical engineering,
• System and interdisciplinary engineering.

Each product, functional element, or vehicle comprises of many different parts typically designed by separate groups of specialists, which can exchange their work using a data cloud and CATPART files.

CATIA V5 part files

CATIA stands for Computer-Aided Three-dimensional Interactive Application, and is a 3D CAD software. CATIA was released in 1977 initially for aerospace industry, but after some time it became popular in the marine engineering. Today it is used in many engineering fields and projects:

• CAM - Computer Aided Manufacturing,
• CAD - Computer Aided Design,
• CAE - Computer Aided Engineering,
• PLM - Product Lifecycle Management,
• 3D

CATPART is the native file format for saving project parts in CATIA 5, while version 6 of CATIA uses a different format. CATIA was initially developed for mainframe computers, but soon versions for Unix systems followed, and in 1998, along with CATIA V5 release, the application became available for Linux, Windows XP, and Windows NT platforms. CATIA allows users to export CATPART and CATPRODUCT files to other formats. Third-party tools for converting and viewing (although not editing) CATIA files are also available.
