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.

To smooth a curve or a selection of CVs

1. Select the curve, or select only the CVs you want to smooth.
2. Select Edit Curves > Smooth Curve.

   To control the amount of smoothing, choose Edit Curves > Smooth Curve > and set the Smoothness option. Lower values do less smoothing. The default value is 10.
