Add doors and windows
Click a wall to place a door or window; drag it along the wall to move it.

Steps
- Pick Door (D) or Window (N) and click on a wall.
- Drag the door or window along its wall to move it. It never overlaps another opening.
- Select a door to change its width, which side it opens to and its swing.
Good to know
- Doors and windows stay on their wall when you move or resize the wall.
