The user can manipulate the curve control points, after drawing the first curve, by using the left mouse button to move the first curve control point and the SHIFT+left mouse button to move the second control point.

CONTAINER_OBJECT_TYPE_ARC

The object is an arc. The arc is drawn by specifying its center, radius, start angle and sweep angle. The user presses the left mouse button at the point where the center of the arc (the vertex about which the arc sweeps) will be. Holding the left mouse button down, the user drags the mouse the length of the radius, along the desired start angle and releases the left mouse button. Press the left mouse button again and drag the mouse through the desired sweep angle. Release the mouse button. Releasing the mouse button will end the operation.
