Hi Chipp, maybe you've got it right there - and yes like Chipp says above MoI is not designed to work with polygon mesh type objects, which is why it does not have a built in OBJ importer.

If you're trying to make a workflow where you're trying to import OBJ polygon data into MoI and then work on it inside of MoI, that's probably not going to work very well unless your objects are very simple. CAD systems don't expect to have surfaces diced up into many hundreds of thousands of little flat facets, CAD systems expect for things like a sphere to be made up of one actual curved sphere surface, for example.

You would want to use a polygon mesh editing program to work on OBJ data polygon mesh data, not MoI.
