What is a .CGR file?
The .CGR file extension stands for a "Quest3D Channel Group File." It is a type of CAD (Computer-Aided Design) file that is specifically created by CATIA, which is a software application used for designing products. The .CGR file format is used to save a visual representation of a design, which could be in the form of a .CATPART (part file) or .CATPRODUCT (assembly file). However, it is important to note that a .CGR file only contains the necessary geometric information needed to view the model. This means it does not include all the detailed CAD data that the original file might have.
Programs that can open .CGR files include: 1. **Dassault Systemes CATIA** - This is the primary software used for creating and working with .CGR files as it is the same application used to generate them. 2. **Okino Computer Graphics PolyTrans** - This is a software tool used for converting between different CAD file formats, which also supports .CGR files. 3. **Open Cascade DMU Reviewer** - This is another program that can open and review .CGR files, typically used in engineering and manufacturing processes.
Additional Information: .CGR files are particularly useful for sharing design drafts for review purposes. They allow users to send a lightweight version of a design without sharing the full, detailed CAD data. This can be beneficial for quick reviews or when bandwidth and storage are concerns. Additionally, .CGR files could be embedded into Adobe PDF documents using the Pro Extended version of Adobe Acrobat, although this feature is no longer supported as the Pro Extended version has been discontinued.
