Hey guys, so im working on a room right now, and its a sci fi room, and i have a box, with normals reversed, but it has no thickness to the walls. and im trying to boolean some details into them, but since the walls have no thickness, it doesnt work. and for some reason, when i try to extract them, the original wall gets moved since it has no thickness to it. what im trying to do is just give these walls some depth so I can easily boolean drill into them
