The Arc Tool tool function allows you to draw a three-point mathematically defined curve in the Trace software.
The Arc has three points: the Initial Position and the Terminating Position (which are called "anchors") and one separate Middle point (which is called a "handle") which can be moved to change the shape of the Arc.
Splines are easier to handle in the software than Arcs for tangification and the conversion process when going to the Cut Preview.
Arcs are still provided in the software for those that prefer to draw with them, but the Convert Arc to Splines process will convert them to Splines for software simplification purposes.
