Hello, I just wondered is there a way to make a single surface totally symmetrical whose mirror plane is defined by a line or a plane surface, so that when I select a bunch of control points on one side of the surface, the control points on the other side of the mirror plane will take the same (but mirrored) values for their position? I’m aware of the “Symmetry” tool, but it only works on a half model that’s mirrored along the mirror plane, making it impossible to have a single surface with symmetrical control points (unless “Merge surface” is used, which complicates or alters the original shape tiny bit).
In the example below, I selected the control points in the right side and the goal here is to have the corresponding control points on the lefts side following the same position, but mirrored along the mirror plane that is defined by the while line. Note that if only the selected control points must affect their corresponding control points on the opposite side, i.e. not the whole opposite side of the surface.
