Viz 2 - How to make ...?

I have a question.
I try to make windows that cut walls. I filtered the largest objects by volume.
I can not cut them and walls. (54.0 KB)

Two things:

  1. Boolean operations work with solids, so you need to make sure the BRep Components outputs Solids not Shells
  2. You need to use a Flatten Multilist node before the Cut, to make sure the cuts are in the same data stream as the wall

Cool! It works! Many thanks
