I'm taking a shot a building FreeCAD since I'm a CAD jockey in my day job and a "good" free CAD solution would be neat. It has OpenCascade as a major dependency, which uses their own license[1]. They claim it's LGPL-like. Would this have to go in free or non-free? Thanks, Richard [1] http://www.opencascade.org/getocc/license/
