i made it!!!
thanks....
regards

OK, I get X from arc that I selected, but how to round result (x=7.2545) to first bigger integer?
and than how to make code to divide that selected arc to X segments?
THANKS....

could you be more precisely? please...

I need lisp that can divide any arc on segments by formula : X= L / 2*sqrt((R^2-(R-0.2)^2);
X - number of segments (first integer bigger than result of formula)
L - arc leight
R - radius of arc
