Hi,
Are you sure about the y formula? y = 0 + (radius - i) why are you adding 0 to (radius -i)? instead of writing solely (radius - i)?
Fred

Hi, You're correct, although I think perhaps I put that in as a placeholder for a future amendment ( substituting 0 for the Y centre coordinate?) Either way 0+ is a pretty redundant! Cheers, Richard
