Since '90, the most people working with CAD (surveyors, engineers, architects etc.) have been using CAD programs by Autodesk with DWG support (or by other software houses, which pay royalties to Autodesk to be licensed using DWG). These software generally run on M$ platforms and many users have a very large archive of DWG files. Also if we had a very good 2D/3D CAD libre software but missing a full DWG support, CAD users still would not use it. But having a full DWG support is really hard... I think quite impossible: DWG is closed and Autodesk change it often (i.e. to support new "feature" for its CAD programs) just, I think, to force users to pay for new releases and to avoid libre full DWG implementations. So the problem here are patents. And unfortunately the solution could not be provided by free software licenses or developers community efforts... This is a clear example showing freedom is a wider and more general "problem", which "solution" needs looking further than the free software cause, involving a wider and more general *political* and *social* approach (*)... (*) That in this case, I think, should means updating the high priority list to fight to get rid of *any* sort of copyright, patents, trademarks and other industrial design restrictions....
