Trying to find a way to edit our map. We have LVT in the kitchen and dining area then the hallway and living room have hardwood floors with a transition piece to the LVT. there is a rug in the living room too. I want to be able to separate the dining room from the kitchen but there are no walls separating it. I also want to edit the room shape of the kitchen and living room to be more accurate of how it is. In the picture added, I want #1 to be added to the living room & #2 to the hallway. Then if possible want to make 3 its own room for the dining room.
