I reported about compability problems in Wine 1.7.x development branch. Now, with 1.7.18 extrude and revolve work normally again! Actually, I haven't found anything which is not working; drawing fonts is a bit ugly now, but that is minor annoyance and may be possible to correct (I have not installed all fonts with Winetricks).

For me, Moi 3D is fully usable in Linux and Blender OBJ import seems to have improved a bit, so it's even easier than before to actually use Moi 3D exports in renders... Only thing is that UV Layout's flatten is needed a lot with high polycount meshes textures, but there is not so much need for remeshing any more.

Moi 3D is brilliant tool! :D
