Decent 3D _in_ PCB would open a large can of worms. Right now, the internal representation is explicitely 2.5D. To make real 3D happen, would likely require extensive changes to the core engine, to the data structure and not the least to the file format. In addition, there needs to be a way to draw models of the components. IMHO, it would be best to do refer all the heavy 3D lifting to applications that were specifically developed for this task. > I made two attempts to make 3D exporters - one for VRML, another for > OpenSCAD (as Bert mentioned in his reply). > The first one was ignored completely, I am very much in favor of a way to connect PCB layout to a CAD work-flow.

If I remember correctly, interest in an OpenSCAD exporter bogged down because of license incompatibilities. However, these issues have been resolved in a good way. Since about January 2014 OpenSCAD is licensed in a way that is perfectly fine for use in an otherwise GPL licensed environment. Let's resurrect the 3D export patient! ;-) ---<)kaimartin(>--- -- Kai-Martin Knaak tel: +49-511-762-2895 Universität Hannover, Inst. für Quantenoptik fax: +49-511-762-2211 Welfengarten 1, 30167 Hannover http://www.iqo.uni-hannover.de GPG key: http://pgp.mit.edu:11371/pks/lookup?search=Knaak+kmk&op=get
