const FSurfacicTolerance & GetIsoTolerances() const
Remarks
Tolerance along Iso U/V is very costly to compute and not accurate. A first approximation is based on the surface parametric space length along U and along V Indeed, defining a Tolerance2D has no sense has the boundary length along an Iso could be very very huge compare to the boundary length along the other Iso like [[0, 1000] [0, 1]]
