Hi,

I am trying to make the array number parametric for the circular shapes (ex pipes or rings). I am trying make the number is calculated automatically when I change the inner radius. Same philosophy whne we create the dimension and link the values (or addind equation) to the other dimensions. For example if I want to create holes around the pipes and if the hole radius is d, and pipe radius is D, the number of the holes that pipe can have should be D*PI/d (Half Circumference / radius of hole). That would be my number in the array.

Is there any way to do it without using VB code?. Thanks for the help.
