Another idea, ....
I think it would be useful with objects that could be marked as interfering objects. Think for example of a ceiling setup - one RC setup was handling the distribution of the ceiling, another the distribution of downlights - Having a cylinder defined as an interference object, and which only mission was, to cut the hole in the ceiling plate, - and maybe even a third rc setup handling ventilation outtakes - again with simple meshes defining the void. A little like interfering Forrest Objects in Forrest Pro. I think this could be useful in many setups.
If it was possible that the inference object could even cut holes in normal non RC meshes, then it would be even cooler.
