The Smooth Curve action smooths out sharp changes in direction in a curve. This can be especially useful for curves created with the Pencil Curve tool and curves created from scan or translated data.
You cannot smooth a closed curve, surface isoparm, or curve-on-surface. Smooth Curves doesn’t change the number of CVs.
