Draw minor and clockwise arcs

When you draw an arc, the specifications that you provide may define two, rather than one arc — one minor (less than 180 degrees) and one major. The ARC command always draws the minor arc by default, in the counterclockwise direction.

For example, if you specify the Start, End, and Radius options, the center can be in two places, which can mean two possible arcs, one minor and one major, as you see here.
