Hello i posted this somewhere else and didnt get a response but this is the category where it should go. So the issue that i dont know it in the picture you see to wall faces circled, the one on the left and right. Well i want those to be joined together in the middle where the line is to form a 45 degree angled wall. Then i would place 2 doors. If you can help that be appreciated. THANKS 
I dont need both faces to come out if you can do it with one that’d be awesome too but i want there to be a perfect edge when they are put together
