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.
