Hi dooki - well MoI does not currently import OBJ or DXF data - MoI currently is not focused on working with polygon model data at all for its own modeling workflow, only on generating polygon output at export time.
That converter will read an OBJ file and then generate all of the polygon edges it finds into it as line segments in a 3DM file, then you can open that wireframe 3DM file in MoI to use as a snapping guide.
