Hi all.
I am playing with the trial version of MoI (Michael, the new version is still valid after three days), and I have a question about booleans. The case is simple. I draw a rectangle, then extrude (a sort of "room"). Then I put a plane on one face, as a "door". Now, if I subtract the door from the room, I don't obtain a "hole". Instead, if I previously deleted the upper face of the room, the boolean operation with the door works as I expected. Maybe I am missing something fundamental about booleans operations in this situation?

Ciao
