Grouping breps for boolean operation

I have a structure with joints. I need first to cut out a bunch of solids (different amount per joint) to get holes, and then spread to grid orienting per pre-defined bounding box.

Bounding boxes and joints data trees are matching, but I am having trouble creating sets for boolean operation.

The part of the definition is highlighted.

Given the current state of things, Clash might be the path of least resistance:

@leopoldomonzani
The data structure match (brep ‘groups’) was needed precisely to speed up the solid difference

Yes, of course, I am aware of that.
