EFFECT

Depending on the edit mode, a GDP Elliptical Arc element is inserted into the open structure after the current element or replaces the current element. The newly inserted element becomes the current element. A GDP Elliptical Arc element is equivalent to a GDP Elliptical Arc 3 element with all Z values equal to 0.

See the write-up for GDP Elliptical Arc 3 (routine pxgdp_elliptical_arc3) for complete details.
