Quadrant Point Position

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

NEW STRA

FPT @

TPT TOP OF ID @

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

NEW STRA

FPT @

TPT TOP ELLI /ELLI1

The syntax always constructs a 2D position.
