Nazdar Joach, what happens when you call IsPeriodic() directly on the m_F(0), rather than converting it to a Nurbs surface first? Right now you are comparing the original surface (which is probably an OnRevSurface (rotacni plocha = surface of revolution if my Czech serves me well)) with a nurbs surface conversion.
