CATIA V5

Catia V5 is a CAD system developed by Dassault Systèmes in 1998, currently widely used in the automotive, aerospace and others industries.

CATIA V5 file extensions are .CATPart and .CATProduct.

CATIA V6 (3D XML)

3DXML is an open-standard proprietary 3D file format developed and supported by Dassault Systemes. 3DXML files are typically created as exports from Dassault Systemes' 3DEXPERIENCE application. The 3DXML file is a zip archive file consisting of a BOM file and one or more 3D representations stored in either XML or binary format. Compact file size allows users to transfer 3D XML quickly and embed it into websites, emails, and various MS Office documents. Therefore, the format is commonly used to integrate 3D data into technical documentation.
