I believe you don't need the J. All you need are two points on the circle and a line known to contain the center. Take the two points and draw a line through them. Draw a perpendicular line through the midpoint. Where your I line intersects the perpendicular line is your radius center. Now that you mention it, I have have called out both I and J in my programs which I guess is erroneous. I suppose G2/3 uses the first option it sees and ignores the rest?
