Array visibility parameter

[pe_simon]

How to set the array visibility to 0, not visible? I have 4 hole, 8 hole and 12 hole. I want it to 65mm in 4 hole, 100mm in 8 hole, 300mm in 12 hole. But don't know how to do it..

I think you could achieve what you need using one parametric polar array (needs to be in a nested family and needs to have a count of at least 2).

You can then control, via parameters, the number of holes in the array and the centreline radius.

This link shows the principles - it is using a repeated pattern for curved insulation but you could easily adapt the principles for holes/voids?

you can't have an array of 0 (or One for that matte 😊). select the object to array and pick the button on the right side of the Visibility parameter.  assign the "visibly" of that object to a new parameter.  Then make the Array. 

once the array is made, you can select the array and pick the array number and make a parameter for that so you can adjust how may objects you have.

Hi, It's a void, don't have the visible item?

sorry, missed the Void part 😊. it looks like you're placing the holes in the Flange? In cases like that I have made 3 separate Flange families and nested them into a parent family. Then you can control the visibility of the nested families as Types.
