Arc with Three Points

General

• You can sketch an arc by clicking three radius points.
• If you do not select a work plane, the arc is drawn on the drawing plane, the plane that is currently facing you.
• The third point of the arc may be either in between the first two points or outside of them. Move the cursor over the second point to change the position of the third point.
