Furniture in Signal Sighting uses a fixed naming convention to allow the Signal Sighting application to interact with the models (described later in this document).

The Signal Sighting application reads these layer names, and uses them to determine what configurable elements exist within a piece of furniture.

Initially, the furniture to be edited must be selected.

On selecting the tool from its icon, the following dialog appears:

This dialog allows the user to select either specific pieces of furniture (single or multiple), or entire types of furniture. For example, the user could select a single signal to set its lights to Green, or the user may select all signals on the up line, and set them all to red at the same time.

Once the furniture to be edited have been selected, the user presses "OK", and a dialog looking similar to the following dialog appears:

Note that this dialog is created based upon the configurable elements available within the selected furniture, so the dialog appearance will vary from furniture to furniture.

The dialog lists all of the configurable elements of the furniture. Selecting items in the dialog will immediately update the corresponding elements in the furniture in the display.

will snap the view to the currently selected piece of furniture (assuming that only 1 piece of furniture has been selected to be edited).

When the user has finished editing the piece of furniture, the user can simply close down the dialog.
