Drawing Exchange Format (DXF)

Drawing Exchange Format (DXF) is a file format designed by Autodesk to allow exchange with their AutoCAD software. While they publish specs it is not an open format as they alone control iterations to the format. Autodesk and the Open Design Alliance sell commercial licenses for accessing DXF files. There is generally good support for DXF in free/libre software.

The Open Design Alliance has a freely available ODA File Converter for converting between different versions of .dwg and .dxf
