is the abbreviation for Drawing Exchange Format.

DXF was used originally as an exchange and database format for AutoCAD. Over the course of time, however, the ease with which it can be interpreted has made it into a standard format, particularly in the PC world.

DXF, too, is able to describe both 2D and 3D data, though the number of defined elements is limited to those types used in AutoCAD.

Unambiguous transfer is generally possible. Difficulties arise due to the fact that line thicknesses and fills can only be defined for specific elements. Consequently, the graphics capabilities are very limited.
