The Change Bezier Point Number tool allows you to change the number of Bezier Points on the sides of certain paths. Any polygon or segment has Bezier points. The number of points initially on a side of a path is set during its construction using the Bezier Point Option Button. This will set the initial number of Bezier points for all sides of the path. If you want to change that number after construction, you can use this tool. See the Move Bezier point tool for an explanation of the effects of moving Bezier points.
