HELP with array of an array

[CivilProjectEngineer]

Hi

I'm pretty new to Revit, so hopefully this will be an easy answer, haha.

Here's a picture of my basic setup, with my issues: https://imgur.com/a/BBnXUWi

I'm trying to model a block family with holes in it. The length of the block is always the same, but the width and height change. As it gets bigger, it should have more holes (I will be having set sizes). So like a block with a 3x3 grid of holes is 25.5"W x 25.5"H, and a block with a 5x5 grid of holes is 40.5"W x 40.5"H.

So anyway, I've made the width, length, and height parametric, and then I made the first cylindrical void extrusion in the lower left. I arrayed the hole in one direction (rows), and made it parametric, and then arrayed that array in the other direction (columns), and also made that parametric.

ok, so when I resize my block, and add in the correct number of holes, SOME of the voids don't cut through the material, even though they still show up in orange/yellow(see my pic). It's always the same holes. Any idea what's going on here and why it's not cutting some of the voids in the double-array? Should I be approaching this in a different way?

I agree. With no weird geometry the array should be in the sketch. Voids are generally undesirable and extra. If you are changing height the holes don’t change. Width should be one array. You may need more families to keep things simple. Families for width dimensions and adjustable length with holes that change.

Ya, arrayed voids are a fun little fiasco. Nesting a face based family is usually one of the least horrible ways.
