BUDWEISER.DWG checks the DWG compatibility
Another tool by XANADU (CAD Studio) with the same name as this blog is the BUDWEISER.DWG drawing. It exists already since 2001 (for older AutoCAD versions), so this is not something brand new, but what is new is the 2010-version of this free benchmark drawing (Budweiser2010.dwg) - released today.
The BUDWEISER.DWG drawing file contains a set of about 30 test cases. They consist of pairs of "reference" and "test" images. Both should look the same. The Budweiser benchmark uses visual comparison to determine the passed/failed results of the individual test cases.
The individual test cases check various functions and aspects of different types of drawing objects in 2D and 3D. All cases were drawn manually using standard AutoCAD commands. So any CAD application claiming DWG-support and full DWG-compatibility should display all these pairs identically.
Well, it should - but in fact, so far no "AutoCAD-clone" software has displayed the full contents of this DWG file. This means that you can expect also incomplete and mangled contents of your own DWG drawings opened in reverse engineered AutoCAD-alike applications. BUDWEISER.DWG can help you to test the real DWG compatibility.
