Hi Alls,
My code is OK, but a few trouble if that code for use with rather far from a circle, or look at attach file "Figure Circle-1" , the line for centering can not over the circle, if you zoom a circle and then use that code it result is ok, the line for centering is over to the circle, or look at attach file "Figure Circle-2".
