The C-B?zier curve is introduced to CAD/CAM to deal with circular arcs, cylinders, and cones. It can precisely represent these conic curves in a B?zier-like way. A conjecture in [Chen and Wang'2003] is that the sequence of control polygons associated with the C-B?zier representation of a curve converges to the curve itself as the curve degree n goes to infinity. In this paper we prove this conjecture.
