HOW CAN I MAKE RENSTRICT AN ELEMENT DEPENDING ON THE NUMERS OF ELEMENTS CREATED BY AN ARRAY

[obranovo]

Hi to everyone. I would like to get help with this.
I want to renstric an element that it could changes only when a parameter of array is modified. so if i created a new number of tower sections  the green element that is the foundation will be  aligned to the new created sections in the array .

If you need the foundation to go up / down with the amount of elements in the array: constrain it with a dimension calculated by the number of elements in the array and the height of the element.

What exactly have you tried? The issue could be any number of things.

Is this a Drafting View with Detailed Elements? A Family? Solutions depend on what you're working with.

For instance, you could do something like this with Global Parameters:

But you would have to change your Tower Section family such that the array is baked into the family instead of arrayed in the project file - for some reason project arrays can't be defined with a parameter.

Are you saying that you want the foundation gets deeper when the tower gets taller? If so, you just need to associate the foundation depth with the array parameter via a formula.

Im working with a family.
Thank you I will try it
