Glad it worked.

Back when Maya 3 was out and desktop computers did not have the CPU performance and memory capacity of Cray super computers NURBs was the ONLY way to model.

I am not gonna kid you. Maya's NURBs tools are full of problems, because they appear to be watered down versions of what were part of a more powerful professional surfacing application studiotools (now autodesk automotive).

But they are still very powerful, you just have to work within their limitations.
