Arc Input

When you want to create a curve that is perfectly circular, the Arc input can help. This input uses three points, clicked with the mouse, to create the arc. The first and second inputs should be on the arc that you want to create. After the second click, moving the mouse will draw a circular arc between those first two points, running through your mouse cursor. Once you have the desired arc, click the mouse a third time, which ends the arc input.

This program, like most drawing programs, allows Bezier forms to take up to 90 degrees per node. If the circular arc you create goes around more than a quarter of a circle, multiple nodes will be added.

You can edit the nodes which the arc input creates as you would any other.
