Arc - Center and Radius


Creates an arc by defining its center, a point on its circumference, and the start and end angles.

  1. Select the arc centerpoint and a point on the circumference of the circle from which the arc will be cut. You can also specify the radius, diameter, or circumference in the Inspector Bar.
  2. A dotted line appears from the centerpoint. Move the cursor to set the arc start angle, or enter the angle in the Inspector Bar.
  3. Move the cursor counterclockwise to draw the arc, or enter the end angle or arc length in the Inspector Bar.
