Hi Phr0stByte, I've heard of a lot of problems in the past with Maya's IGES import, I think it has had bugs in it for quite a long time now. Unfortunately it does not seem to have been a priority for them to get it fixed up...
It sounds like maybe .step / .stp format import may be newer and work better?
Most of the time exports to Maya use polygons and .obj format.
Thanks guys. I use linux, and come to find out - no direct-connect for maya on linux. That really sucks... I will check my Maya installation at work, and see if it has it - it is a Windows box (unfortunately, the only place I can use MoI too).
