Arc
The Arc tool creates an arc defined by three points—two endpoints and a radius (or curvature)
point.
Note: By definition, an arc created on a circle has a radius equivalent to that of the circle.
Creating an arc
1.
Select Arc from the Curves toolbox.
2.
Create or select the initial endpoint of the arc.
3.
Move the cursor from the initial endpoint, and click to
create or select the curvature point.
4.
Move the cursor from the curvature point, and click to
create or select the final endpoint.
Modifying an arc
Change an arc by dragging any of its three points.
If an arc is defined by basic points, grab the arc away from
the points, and drag it to a new location.
