# modify the divisions by copy node

## Recommended Posts

Hi, everybody.

I have to ask a newbie question.

I want to get a geometry when the first circle have three point,and the second circle have five point, the third have seven.

So what function can i used in value by copy node stamp inputs.

Thanks you!

Hi,

You are approaching it the right way with the copy stamp but instead of giving it a fixed value, in your case 5, you must give it a dynamic value. The local variable of the copy node for the amount of copies is \$CY. This means that if you put \$CY in your stamp value it will increase it by 1 every iteration starting from 0. Because it starts at zero it would mean the amount of divisions would be 0 in your circle so I would add 3 to the expression so that you always at least have a triangle.

OH!

I have try some value,but i forget the basic one.

Thank you so much! Robert!

Or you could change the stamp variable to s=\$CY*2+3
