To create an arc, you can specify combination of center, endpoint, start point, radius, angle, chord length, and direction values. Arcs are drawn in a counterclockwise direction by default. Hold down the Ctrl keys as you drag to draw in a clockwise direction.
The following options are available:
Second Point
Specify the second point (2) is a point on the circumference of the arc.
End Point
Specify the final point (3) on the arc.
You can specify a three-point arc either clockwise or counterclockwise.
Start Point
Specify the start point of the arc.
End Point
Using the center point (2), draws an arc counterclockwise from the start point (1) to an endpoint that falls on an imaginary ray drawn from the center point through the third point (3).
The arc does not necessarily pass through this third point, as shown in the illustration.
Angle
Draws an arc counterclockwise from the start point (1) using a center point (2) with a specified included angle. If the angle is negative, a clockwise arc is drawn.
Chord Length
Draws either a minor or a major arc based on the distance of a straight line between the start point and endpoint.
If the chord length is positive, the minor arc is drawn counterclockwise from the start point. If the chord length is negative, the major arc is drawn counterclockwise.
Center Point
Draws an arc counterclockwise from the start point (1) to an endpoint that falls on an imaginary ray drawn from the center point (3) through the second point specified (2).
Angle
Draws an arc counterclockwise from the start point (1) to an endpoint (2), with a specified included angle. If the angle is negative, a clockwise arc is drawn.
Included Angle
Enter an angle in degrees or specify an angle by moving the pointing device counterclockwise.
Direction
Begins the arc tangent to a specified direction. It creates any arc, major or minor, clockwise or counterclockwise, beginning with the start point (1), and ending at an endpoint (2). The direction is determined from the start point.
Radius
Draws the minor arc counterclockwise from the start point (1) to the endpoint (2). If the radius is negative, the major arc is drawn.
Start Point
Specify start point of an arc.
End Point
Draws an arc counterclockwise from the start point (1) to an endpoint that falls on an imaginary ray drawn from the center point (2) through a specified point (3).
Angle
Draws an arc counterclockwise from the start point (1) using a center point (2) with a specified included angle. If the angle is negative, a clockwise arc is drawn.
Chord Length
Draws either a minor or a major arc based on the distance of a straight line between the start point and endpoint.
If the chord length is positive, the minor arc is drawn counterclockwise from the start point. If the chord length is negative, the major arc is drawn counterclockwise.
End Point of Arc
Specify a point (1).
