Purpose¶

This class represents a NURBS curve based on the knot vector and the control points that you specify.

The Knot Vector field specifies a floating-point array of values; the values are the coordinates of the knot points in the curve, and you must enter them in non-decreasing order.

The Num Control Points field specifies the number of control points the curve will have and will use the current coordinates that are indexed from the Coord Index field.
