What is a CGR file?

CAD file created by CATIA, a CAD application used for product design; saves the visualization of a design (.CATPART or .CATPRODUCT), but only stores the geometrical information required to view the model instead of all the CAD data.

More Information

CGR files are used for sending design drafts for review. They can also be inserted into Adobe .PDF documents using the (now discontinued) Pro Extended version of Adobe Acrobat.

Quest3D Channel Group File

Developer Act-3D
2.4  |  5 Votes

File created by Quest3D, an engine used to create 3D programs that is now discontinued; contains a group of "channels," or properties for the flow and display of objects, models, surfaces, textures, properties, and animations; used to store product visualizations, games, tutorials, animations, user interfaces, and immersive environments.

More Information

CGR files are always stored with complementing .IGR files, which contain the location of channels within the Quest3D Channel Graph layout pane. If the IGR files are missing, the channels will use a default layout and may be difficult to view.

NOTE: CGR files are used in games such as Audiosurf, Leo, and The Endless Forest.
