1) I`ve tried to import obj to carve it into mold template made in MoI - OBJ was to heavy even after decimation - I can`t go lower. It was very brilliant idea but it`s too heavy to work in that way
2) I`ve tried to export subd for Michael but file has got 300MB, I can`t do booleans merge on it (at all).
3) When I`ve builded that mold I controled all draft angles and pins are directed in same angles like parts inside mold. I don`t know how in MoI I may control those draft angles (in polygons I check it inside Zbrush and create locators which can change world orgin and world direction temporary. I work on many different direction to be sure that every part has got right angles).
4) I know that should be created from scratch in MoI3d but I`m working over few million polys scans creating those parts and I have very low budget that`s why I`m doing it in that way. In other way I would bought Alias, Geomagic Wrap/Design X and Solidworks. I`m doing it with low budget and I produce many parts in that way.

Thanks for your tips.
