Arc

This entity is specified by its center point, the two endpoints, and its normal.

To create the arc:

1. Choose Sketch ‣ Arc.
2. Left-click one of its endpoints.
3. Then release the mouse button; the other endpoint is now being dragged. The center is also being dragged, in such a way as to form an exact semi-circle.
4. Left-click again to place the other endpoint.
5. Drag the center to the desired position. The arc is drawn counter-clockwise from the first point to the second.

The arc must be drawn in a workplane; it cannot be drawn in free space.
