Auxiliary Views (Curved Edges)

Surface A. LOS. E. Auxiliary Views (Curved Edges). The same procedure (steps1-10) discussed before applies for curved edges. However, curved edges have no corners, so we take points on the curved edges and treat them like corners. The more points we take, the better the drawing of the
