.CATDRAWING File Extension
What is a CATDRAWING file?
Drawing created by CATIA V5, a 3D CAD manufacturing application; stores a 2D drawing of a mechanical part and assembly; includes different views of the part, such as Aligned Section, Detail, and Auxiliary.
CATDRAWING files are linked with corresponding .CATPART files upon creation. If the matching CATPART file is moved or deleted, you will get an error and will not be able to open the CATDRAWING file.
