Point 1 of the arc is its center. An arc's center is the center of the circle of which the arc is a part.

Point 2 is one end of the arc. The distance between point 1 and point 2 is the radius of the arc. Points 1 and 2 also establish the circle that the arc is a part of.

Point 3 can optionally be located by typing @num (where num is a number of degrees) then left-click ( Locate ). Alternatively, you can left-click ( Locate ) without typing the desired number of degrees.

If you type an angle (@num) before locating point 3, the point location target ( ) snaps to a point on the circle that is the typed number of degrees counterclockwise from point 2. Left-click ( Locate ) to accept that point.

The length of an arc is the distance counterclockwise along the arc's circle from point 2 to point 3.
