I think the values must be bigger I tried C = Intersect(circSurfOuter, lattSurfEuler_3, 3, 150) and D = Intersect(circSurfOuter, lattSurfEuler_3, 0, 300) and got points. I think to use conic is better. ie: e: Conic(circSurfOuter(0), circSurfOuter(1), circSurfOuter(2), circSurfOuter(3), circSurfOuter(4)) f: Conic(lattSurfEuler_3(0), lattSurfEuler_3(50), lattSurfEuler_3(100), lattSurfEuler_3(150), lattSurfEuler_3(200)) Intersect(e, f) really I think that to use conic from beginning instead curves is better]]>
