The best way is to work properly and and data well organized, Datatree with surface and datatree with brep, tags …
As it is not here a way to deal with that. As it is also not ordered I add to check which center gravity is near the other center of gravity …
Then place Tags not in thin air but on a real surface, so I reuse my tools (check the displacement I used (0.254), it must be half the thickness.
I also added a Bin Packing, not necessary but could be useful.
I suppress the Hull component, not sure it is useful here as you have a nice surface.
