Need fuctionality within PATCH to create an nSided tangen or smooth fill surface with constraint curves. This would be a surface with 5 or more sides as well as just 3 sides. The need for this is more common than you might expenct. 5 sided surfaces are common in fillet intersections. The fillet tool is an example but would not be a sucessful way to create a 5 sided surface. Other systems offer unlimited sided surfaces.
