Hi PAQ,
Here's the OBJ I tested with that had the normals option unchecked in the export.

Also, Michael had mentioned the Integritywares application. You said you have Max and they have a plugin that I believe only costs roughly $200.00

I think it actually makes smooth NURBS surfaces as a result. I have been excited about seeing this crop out in something that we could utilize.. Just hoping at this point. I contacted them about a standalone option, but I dont think they were interested..
