Description

Draws cubic spline curves from fit points (points on the spline curve).

Usage

1. Check the "Closed" check box in the options tool bar if you want to create a closed spline. Closed splines are continuous closed loops.
2. Specify the fit points. You can remove the last fit point by clicking the "Undo" button in the options tool bar.
3. Hit escape or click the right mouse button after setting the last point to confirm the spline shape.
4. You can not create another spline or right-click again to terminate the tool.
