you are right ,visose. thank you . i managed to see the index 0 value in every path of these circles , and i found not everyone of them is at the botom .some of them were at the middle and the last ones at the top . then i simply changed the loft options from "normal" to "straight" ,it seems work .but i never wanna to loft ererything others with a "straight" option . i tried to "control" the loft orders ,but it's not a easy job for me to do now ,, thanks in anvance, alpha
