Hi Burr,

> I was wondering if ther was a Rhino command that would do this in this situation.

Rhino's Patch command should do that, on the version that I posted that has a dividing line running down the middle and the long edge split into 2 pieces. You would run it in 2 separate passes though, select 3 inputs at a time - 2 edges and the centerline curve.
