Guys, This is in no way the beginning of an argument with you, Frank, because you are right about the generality of the question AND about Variable Section Sweeps. After 14 years of using Pro, I still think they are the coolest tool imaginable, especially when utilizing multiple trajectories and the extraordinary capability of a Graph. However, each tool is ideally adaptable to a different class of situations, and a Smooth General Blend might be the tool of choice in the wing situation. (Entering the angular rotation relative to the Z-axis is probably quicker and more direct than what would be necessary with a VSS.) David
