I know the following can be done using several objects, but can it be done with a single object?
Start with a massing block, then use the opening tool to make two parallel N-S "tunnels" through the block. Now go to the East surface and try to make two E-W "tunnels" that will go through both the 2 N-W tunnels, and the 3 NW walls. Is there a way to get the opening through the center N-S vertical "wall"?
