A Spline may be openRed-14-1b or closedRed-14-2.

To show the spline-handlesRed-14-3, click the Spline.

The direction of the spline is normal to the spline-handleRed-14-3

The curvature of the spline is proportional to the length of the spline-handle

The curvature of the spline is symmetrical to the two sides of the spline-handle.

To hide the spline-handles (default), click the Spline again.
