What is a MODEL file?

A MODEL file is a 3D model created by Dassault Systemes CATIA, a 3D CAD and CAM program. It contains a representation of a mechanical structure or part of a structure. CAM machining tools use MODEL files to machine corresponding real-life parts and structures.

More Information

Dassault Systemes CATIA (which stands for Computer-aided Three-dimensional Interactive Application) is an application that mechanical designers and engineers use to create and test tools, structures, machines, and machine components. CATIA is used in the aerospace, defense, architectural, and industrial machining industries, among others.

Versions 4 and below of CATIA save the 3D models users create as MODEL files. Version 5 saves users' models as PART files.

How to open a MODEL file

You can open a MODEL file in Dassault Systemes CATIA (Windows, Linux). If you want to convert a MODEL file to the PART file format used by CATIA version 5, first open the MODEL file in CATIA version 5. Then, copy and paste the file's contents into a blank PART file.
