Hello All,
I am a bit lost here, I admit I am not an expert and I am still learning with every definition.
here we go: i have 54 modules (it could be more or less, i choose 54),

7x modules
What I would like to do is to have different sets of this groups in the 54 modules .
for example: 2 groups of 1 module +4 groups of 5 modules +3 groups of 6 modules + 2 groups of 7 modules.

this is far from my usual use of GH and so i am really clueless, any tip for a starting point, where and what to look will be nice. grid13.gh (25.3 KB)

Youâ€™ll need to include void(s) in something like this:
