I have a complex organic shape that I built with the Patch command. Basically it is a half dome with an outside profile. The “dome” is derived from several cross-section open curves that all touch on either end on a closed curve “rim”. Problem is that the resulting trimmed surface’s edge matches the “rim” in the x and y axis, but not z. I have something that from the top looks perfect, but when seen from the side looks like a Pringles potato chip. The “lip” is wavy. I need to have the edges all bound by the “rim” curve in all dimensions so that I can attach to a flat flange.
The Patch command creates a surface from the cross-sections and then trims it with the rim. I end up with no control points on the edge. How can I force the edge of the surface to conform to the rim in all three dimensions so that it will mate to a flat flange?
