No this example is imported in blender with a special Blender's build, that import 3dm file. here more info about. https://blenderartists.org/t/branch-soc-2014-nurbs-update-to-master/1207889/

But what I suggest is Blender can handle well Nurbs and maybe the best way is using it's own native Nurbs code to exchange file and not the OBJ format
