Hi Pat,
if you wish to turn your design into a real object via a wax carving mill or a rapid prototyping machine you will need to convert your Nurbs curves into a mesh first. For a mill this is then converted into a set of toolpaths by a postprocessing program, I am not sure about RP , out of my league!
