Isoparametric curve

Tolerance for Boolean Add Along Surface Edges?
Is there an accepted way to compare two surface edges to see if they are within tolerance for a boolean add operation? I'm trying to create an approximate offset curve along a surface - within tolerance - so it can be used for trimming and other operations. In this image the input curve is an isoparam (degree-3) and the…
