Can't make a solid difference out of a collection of breps

[Ly_Ly]

The top object, is the result of the solid difference, which for whatever reason doesn’t get out the spheres

But the analogous command bool difference within rhino, works fineish…

please post the .gh file with internalised geometry.

actually it seems that it does work, but I get a different output for each pair… so I need a way to join those spheres in one single brep, as I found suggested in past threads… but the brep join, and solid join, still consider the objects as a collection rather than a single object

Here is the file gh
4rhinoforums.gh (12.2 KB)

whereas I want theese cheese endresult, but within grasshopper, not rhino

you need to flatten the second input of Solid Difference.
