XANADU has just released a new version of the well-known benchmark drawing - BUDWEISER.DWG. The Budweiser2008.dwg tests the DWG2007 file format with drawing objects from plain AutoCAD 2008.
 
You can test the compatibility of your non-Autodesk CAD application claiming "100%-compatibility" with DWG file format.
