If you click the right mouse button inside the room when you are in layout window, you can select the Move command, that allows you to move the room in a different position of the project.
With this command you can also rotate the room in order to achieve a different orientation of the room, thanks to '-' and '+' keyboard buttons (clockwise and anti-clockwise).
When the user moves the room, its content obviously moves along with it (furnishings, 3D objects, groups, lights, dimensions and texts, …).
