CGR - CATIA Graphical Representation.
a CAD format mostly used for Digital Mock-Up (DMU). Catia modules DMU Navigator, DMU Space Analysis, DMU Fitting Simulator, DMU Kinematics Simulator and DMU Optimizer supports CGR files.
- CGR files can be load faster
- CGR files are small (10% of original model size)
- only for visualisation, no geometry
- no relations and connections between objects
