Polygon Pencil
The Polygon Pencil control allows you to draw a series of points connected to one another as dictated by your hand movements.
Rather than drawing the connections at specified points in straight lines, the polygon pencil adds points to the shape as the mouse moves. The polygon objects produced by using the pencil are the same as the objects used by the regular polygon drawing methods, they just contain more points.
