I just found Sweet Home 3d - an open source 3d interior design application. http://www.sweethome3d.eu Though its not really intended for general purpose architecture, i think its quite worth discovering. Maybe it could be a starting point for real cross-platform open-source BIM ? SH3d already has parametric objects, it can import .3ds and .obj. Yorik, can java app theoretically be integrated in freecad? Together with Processing <http://processing.org/> it could rockn`roll in the future. Or is it just a sweet dream?
