Hi all, as for GRASS's use, we have a partial implementation as v.in.redwg for GRASS6 and 7, https://trac.osgeo.org/grass/browser/grass-addons/grass6/vector/v.in.redwg
This has been left as a user-compiled addon module partially because it is not fully developed to take advantage of all that LibreDWG can do, and partially because GRASS is GPL2+ not 3+. I would not ask for a license change on our behalf, but fyi that's where we're at. i.e. even if there was a license chance we wouldn't incorporate it immediately as our interface to redwg is not complete. Note we also ship the source code for (but not build) v.in.dwg which relies on the non-Free OpenDWG toolkit, and do build by default the v.in.dxf module for classic dxf+3D (no external dependencies for that one). What's the situation/experience/state of the art like with BRL-CAD's implementation? thanks for keeping it alive, Hamish
