>> Last time I tried FreeCAD it seemed like a bunch of really good tools that had kind of been thrown in a bag and shaken around a bit. All the bits were there but it just seemed so clunky. That's my impression too - and it tends to crash. If you look at how FreeCAD imports DWG files for example, it runs an external instance of a DWG->DXF converter built from (I think) LibreDWG, and then it uses their other python DXF importer to bring it in. In a way it makes sense because LibreDWG is GPLv3 only (not LGPL) so they can't directly incorporate it. But the awkward way it gets used feels like the way a lot of FreeCAD is put together. OTOH it can do a LOT and it is Free Software.
