Devices and levels in buildings

When you add a device to a building, by default, the device is associated with the default level if one has been specified. Otherwise, the device is assigned to the first level. However, you can change this and associate the device with any other level, or several levels at the same time.

More facts:

If you readjust the boundaries of the building so that it no longer covers the device, the device is no longer associated with the building.
