RE:NURBS blend curve
Yes, certainly I can use lines and arcs to get the same effect; my question was more about the underlying math and what will give the result while minimizing acceleration and pressure angle.  Going from an arc to a straight line, or one arc to another, is an abrupt change in acceleration, which is never desirable.  A spline by its nature gives a varying curvature, which I think would be the lowest energy curve.
