DXF stands for Drawing Exchange Format (or Drawing Interchange Format) and was created by AutoDesk for their AutoCAD and AutoDRAW CAD systems.

There are ASCII (plain text) and binary variants, since AutoCAD Release 10, of DXF. The ASCII variant is apparently more prominent. Both ASCII and Binary versions can be identified using the same tag as the DWG format. Binary DXF is not to be confused with DXB, a related but distinct format.
