Sketcher BSplineComb

Description
Shows or hides the display of the Curvature Comb of a B-spline curve (see B-spline).

The curvature comb indicates the curvature of the spline at every position. The higher the curvature at a position, the more is the the comb away from the curve. For positive curvatures ("turn to the right"), the comb is at the other side of the curve than for negative curvatures.
