If you design the counter top as a room, you can insert a staircase. Remove the staircase, then export and import the counter top for further use.

thanks, but I don't understand. the ceiling is obviously pierced by the staircase ... but I imported a vaulted ceiling into the obj. that the staircase does not hole ... in practice I have to make the circular hole that connects the two floors on the obj. imported .... is it possible?

in essence there is something similar to the "invisible box" that he uses on the walls, to hide a part of the obj. what am I using?
