CAD Files

Computer-Aided Design (CAD) files are typically created with CAD software applications. They may store three-dimensional designs, which are also known as models, assemblies, or parts, as well as two-dimensional designs, also called drawings.

CAD file extensions include but not limited to .STL, .DWG, .DGN, .DXF, etc.
