I think FreeCAD is a great ability to derive 3D models of Moi3D in 2 D drawings.

FreeCAD is a general purpose 3D CAD modeler.
The development is completely Open Source (GPL & LGPL License).
FreeCAD is aimed directly at mechanical engineering and product design,
but also fits in a wider range of uses around engineering,
such as architecture or other engineering specialties.

I haven't checked it out yet, but I saw what you meant when I read the wiki page http://sourceforge.net/apps/mediawiki/free-cad/index.php?title=Feature_list . It does a lot of things that you wouldn't expect in 2d and 3d. That obj export in a cad program is strange- but good. You mean something like the request for text on a cylinder edge could have been done in Freecad, exported in 2D and extruded in Moi? Of course, I'm reading a lot into the timing of your post, but this looks very interesting. Thanks very much for bringing this up.

Probably not so much for stuff like that, more like if you wanted to produce 2D drawings for printing and construction with things like dimensions and annotations on them.

You could export your MoI models into FreeCAD and then use stuff in FreeCAD to generate the final 2D drawing.

Also it looks like it has a hidden-line drawing generation feature, which tends to be hard to find in free software, so that is interesting:
