Selecting OPTIONS from the menu will present you with the following options:
The NURBS Curve by Through Points options menu
The NURBS Curve by Control Points options menu
Allows you to append an additional node (when in Through mode) or vertex (when in Control mode) to the curve.
Allows you to change the position of a node (when in Through mode) or modify vertices (when in Control mode) that had been placed previously in the curve.
Allows you to insert new node points (when in Through mode) or modify vertices (when in Control mode).
Allows you to remove an existing node from the curve (when in Through mode) or a vertex (when in Control Mode).
This option is available in Through mode only. It allows you to modify the curve with a new tangency condition. An endpoint is selected from the Position Menu.
This option is available in Control mode only. It allows you to change the weight of a selected vertex. The new weight value must be greater than zero.
This option allows you to reverse the direction of the curve.
This option allows you to change the degree of the curve from the default degree value of 3. The new degree value must be within the 1-8 range. A NURBS Curve may not be degree reducible.
