Software That Opens & Edits CGR Files (4 Tools, 2026)

CGR (CATIA Graphical Representation) and its web-friendly packaging format, 3DXML, are lightweight, tessellated 3D visualization formats developed by Dassault Systèmes. Engineered to enable digital mockup (DMU) reviews of massive industrial assemblies, CGR files strip away the heavy, precise mathematical B-Rep (boundary representation) solid definitions. What remains is a highly optimized polygonal mesh shell that can be loaded in thousands of instances concurrently inside CATIA, ENOVIA, or web-based PLM platforms to perform clearance checks, clash analysis, and layout coordination.

Frequently asked

Can a CGR or 3DXML file be edited or parsed back into solid geometry?
Direct editing is not possible because the exact solid boundaries are replaced with a flat triangulated mesh. However, designers use specialized CATIA reverse engineering modules or third-party mesh-to-solid tools to rebuild exact NURBS surfaces on top of the CGR polygonal shell.
What is the role of 3DXML in modern enterprise PLM systems?
3DXML acts as the universal viewing standard inside Dassault's 3DEXPERIENCE platform. It allows purchasing managers, structural testers, and executive stakeholders to view, rotate, section, and measure full multi-level product models directly in their web browsers without a local CAD license.
