I've begun coverting some of my old models so they can printed in 3D. It has proven alot more complicated that I imgained, its whole diffrent set rules and objectives form makeing models just for images. Most of my models are made up of a large number of separate but overlaping objects, some of them simple, some very convoulted shapes. Stitching all these parts togther into one mesh has proven difficult and time consuming. I use Maya and unfortunatly Mayas booleon function is pretty crap, the only way that works thus far has been cutting out internal geometry and stitching objects together one at a time. I'm after any advise to speed the process along.
