Its almost what i want, but not exactly what im looking for.
Actually, in your version, you can decrease and increase the hole size on each diamond, but instead of this, i would like to use extrusion component to make diamonds completly full on the lower part of the pannel and empty (like where you put the line) on the top of the pannel. So i think scale component is not the right tool for that, because i need to manage the thickness of the pannel and not the size.
Is it clear for you?
Thanks a lot.
