Hello Michael,

You are correct that my question is improperly formed. Is there some sort of common equation that defines a NURBS curve no matter what its "G" ness is? If you would imagine a bowl shape that has a different set of inner and outer curves I'm trying to find out if a relationship or some ratio can be mathematically expressed between those two curve sets that are revolved to form the bowl. If the inner and outer curves were arcs a more understandable relationship could be defined, i.e. a 30mm outer arc and a 15mm inner arc forming a bowl shape can have a relationship defined as a ratio of outer to inner curve using radius. Thanks.
