CAD Files

CAD (Computer-Aided Design) files may contain 2D or 3D designs. They are generated by CAD software programs, which can be used to create models or architecture plans. 2D CAD files are often referred to as drawings, while 3D files are often called models, parts, or assemblies.

Common CAD file extensions include .DWG, .DXF, .DGN, and .STL.
