What is the BREP file format?
A file with the .BREP extension is a file known as 3D Model. It belongs to the 3D Image Files category. This format is associated with Open CASCADE.
The reliable way to open a .BREP file is with software that recognises this exact format, rather than guessing from the file name. If you are not sure what created a file, our file identifier can read its first bytes and name the real format, even when the file has been renamed.
We are still gathering the list of programs that open .BREP files. A fully verified, hand-written description of this format is being prepared; until then, the details on this page are drawn directly from our database.
