I got it from another way… much better!
But, pay attention, when you work with parts, there is a “cheating”.
if you check EXCLUDED (see red arrow), another ghost part is created.
So, I got another nodes to leave only REAL PARTS in the lists.
ROOM AND PARTS.dyn -> listing all parts
ROOM AND REAL PARTS.dyn -> filtering somethings and filtering ghost parts
