Surface extraction

We have a couple of interns working on Rhino designing a control counsol for us. They have designed a control paddle that needs to be molded. I can import the iges file into SW and make a solid with no problems. The vendor would now like us to give them a surface model so they can split it and create the mold. I tried shelling the model but that was not what they wanted. Apparently he wants just a surface model and both he and I are unable to create one. -I have never worked with surfaces before, Just solids. SW help tells me how to use  the Surface Extraction Property Manager....but I can't find it on my machine to attempt using it. I also am not sure that is the best method to use.

Can someone suggest how to create a surface model, either from importing the Rhino surface, or by extracting a surface from the SW solid model?

Thank you
