Quadrant Point Position

A quadrant point of an existing circle can be used for point construction. This will be the extreme TOP, BOTTOM, LEFT or RIGHT of the circle. For example

Quadrant points of an arc or ellipse may also be identified. If an ellipse is rotated, the nearest extreme of the ellipse will be selected. For example
