Wish 3: I wonder is there a way to select an entire (or partial) row of control points and have a command to distribute them evenly along the control polygon? Especially if it’s possible to do this with just a few control points (i.e. not the entire row), it should greatly help to improve the fine adjustment of surfaces. It would help even with fixing the existing top and bottom surfaces of the 3d model from this topic Closed polysurface has overhanging surfaces when shaded or rendered , optionally followed by the “Match surface” command to make sure they will join with the vertical surfaces.
