Here are the wires Dave. Contour render apparently only works with polygons so no isolines get diplayed for the NURB's part. I went with 16x16 nurbs surfaces and 16x2 for the lofts and rounds. Mesh density is important when applying rounds to the trimmed surfaces or you will get visible seams.

I went with NURB's just because it was fast and easy. But in the end I will want the model to be all polys and unified. With this as a guide to model over it will be easier. For now though it works.



The NURB's part consists of an inner and outer tube that has the holes trimmed, a loft from the outer to inner tube for each hole, and a round (.04) on the top of each hole. So there are two patches for each hole and two trimmed surfaces for the inner and outer tube.
