Sure, but it's not me who actually need it. My dad also has N900 and he need some program that will open autocad files.
From 1982 to 2007, Autodesk created versions of AutoCAD which wrote no fewer than 18 major variants of the DWG file format, none of which are publicly documented.
There are no open source viewers for DWG files since the licensing of the libraries needed by lx-viewer[38] now restricts their use to members of the Open Design Alliance.
