•
Example 1: The arc ring midpoint is picked at point D, dragged upward
to point D
′, and then placed at point D′. In this example, the number of
radians in the arc ring decrease, and the radius of the inner and outer rings
will increase.
•
Example 2: The arc ring midpoint is picked at point D, dragged
downward to point D
′, and then placed at point D′. In this example, the
number of radians in the arc ring and both radii increase.
