Hi Phiro, sorry no I'm not expecting to have that kind of non-sub-d .obj import. The problem is that NURBS solids are not intended to be made up of say a hundred thousand little tiny flat faces. There is some overhead in how NURBS surfaces represent faces with an "underlying surface" and then trim curves that mark areas of the surface as active or holes. So each surface in a NURBS solid is more complex (but can do more) than a polygon in a poly modeling program. A model with a hundred thousand little tiny flat surfaces is very heavy and unwieldy when represented as a NURBS object.

A NURBS model should have larger smooth surfaces in it, like a sphere for example should be just one exact sphere surface with a trimming boundary on it, not a whole lot of little flat facets.

If you have an .obj file that you want to edit as polygons, then MoI is just not the right tool to use for that job. It is not designed to work with that type of model structure. You should be using a polygon mesh modeling program to work on that kind of data, it will not work well with MoI.

Since sub-d smoothing generates larger smooth surfaces, it's the type of import that does fit ok.
