The Spline Curve Tool function allows you to draw a four-point mathematically defined Bezier/Spline curve Bezier/Spline Curve in the Trace software. The Bezier/Spline Curve is defined by four points: the Initial Position and the Terminating Position (which are called "Anchors") and two separate Middle Points (which are called "Handles"), which can be moved to alter the shape. |
