Family which doesn't update array void.

[Tabz]

Hi all,

I've set up a ceiling family which consists of a tube which has voids to show the cutouts at the top so that it can be hung to a track. I've created a few parameters and they all work fine. As you update the length of the tube the cutouts adjust accordingly and cut the tube panel, thats fine. But when i update the height from FFL only the first cutout goes with it and the remainder stay behind.

I need some help on trying to get all of the voids to update when i change the ceiling height and also how do i grey out the cutouts parameter so that it becomes non editable, as i have put in a formula for the cutouts.

Appreciate any help.
