Choose Center.

Center of arc: Specify the center point of the arc.

Angle · Length of chord · <End point>:

To define the arc by its endpoint, specify the endpoint.

 

  1. Specify the center point of the arc.
  2. Specify the start point of the arc.
  3. Specify the endpoint of the arc.

To define the arc by its included angle, choose Angle and specify the angle.

To define the arc by the length of the implicit chord connecting its start and endpoints, choose Length of chord and specify the length.

To specify the length of the chord

Choose Length of chord.

Length of chord: Chord length can be interpreted in two ways, both of which relate to the implied circle defined by the arc. A major arc is the implied circle minus the portion specified by the chord length. A minor arc is the portion of the circle specified by the chord length.

To draw a minor arc in a counterclockwise direction from the start point, enter a positive value. To draw a major arc in a counterclockwise direction from the start point, enter a negative value.

 

  1. Arc with chord length of 5 (minor arc).
  • Arc with chord length of -5 (major arc).
