That would probably help out a lot to use as a reference.

To use the generated .obj file in MoI, you can use the OBJ to 3DM wireframe converter here: http://moi3d.com/wiki/Resources#Obj23dmWireframe_converter

That small converter program can read in an .obj file and then generate a 3DM file with lines in it for each of the polygon edges. That would give you a reference that you could use to snap on to for drawing some curves or things like that in MoI.
