I'm trying to make my very first dungeon, called Darkhold castle.
I'm facing a problem everytime I want to make big rooms with doors and walls in common with different rooms.
This is the map that I'm doing right now:

Maybe am I using the wrong asset?
You can't even put walls on the middle of the room, which should be very useful.
Am i wrong or is a limitation of this editor?
Sorry If the question seems obvious for you guys, but I just started using this editor.
Thanks a lot.
Regards
