The Curve function allows you to draw a four-point mathematically defined Bezier/Spline Curve in the Trace software.
The Bezier/Spline Curve is defined by four points:
Initial Position (called an Anchor)
Two Separate Middle Points (called Handles) which can be moved to alter the shape.
Terminating Position (called an Anchor)
Splines are easier to handle in the software than Arcs for tangification which makes the cuts smoother between arcs.
The Convert Arc to Splines process will convert the Arcs to Splines for software simplification purposes.
Arcs are provided for those that prefer to draw with them.
