Hi, I am not sure whether everyone is aware of the fact that the Free Software Foundation (FSF) has identified the lack of a free DWG reader as a priority project (http://www.fsf.org/campaigns/priority-projects/) and links to libredwg: http://www.gnu.org/software/libredwg/ which is based on libdwg: http://libdwg.sourceforge.net/ Note that the aim is to only create a parser to read and import dwg, as writing it would not only be hard to implement for an undocumented format, but also further contribute to the problems arising from the dominance of a propietary, closed format and the various attempts to implement it without knowing the structure. Cheers Lars.
