: CURVE : Change:RepresentationShortcut :
NoneThis command changes the representation (polygon, Bézier or B-spline) of the target curve or curve set. The shape of the curve will be preserved in the change as much as possible.
When changing a B-spline/Bézier curve to a polyline, you may specify how accurately the change is done. The command asks how many points the resultant polyline curve is to have.
A B-spline curve may always be changed into a Bézier curve without changing shape. However, the change from Bézier to B-spline may alter the shape of the curve slightly. If the Bézier curve has originally been converted from a B-spline curve, and it has not been subsequently edited, the reverse conversion will not change the shape.
