is the file format of AutoCAD.

Due to the broad use of AutoCAD, it gained such an importance that a consortium was founded (http://www.opendwg.org) to establish DWG as a standard format.

DWG 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.
