In my on-going quest to build AN fittings, I have a need to build sweeps tha follow a curve. Try as I might, I cannot draw a curve that is normal to the plane of the entity I want to sweep. The curve is always parallel to the surface of the entity. Obviously, I am missing a very important conceptual idea, but I cannot determine what it is. I thought perhaps changing which plane I begin the sweep from might affect it, but so far, I am not able to do it. Any help or amazing insights will be greatly appreciated.
