User Interface


	Navigation Bar Displays the path of the active element, when navigating through your system. See Navigation and Selection Behaviors.
	Architecture Tree Displays the functional, logical, or physical system. See About the System Architecture Tree.
	Work Area Contains the fault tree representation. See About Fault Trees.

Navigation and Selection Behaviors

Depending on the performed actions between the architecture tree, the navigation bar, and the work area, the following updatings appear:


Location	Action	Description
From the architecture tree	Double-click a reference	The navigation bar displays the path of the active element. The reference becomes the root of the displayed architecture tree.
	Double-click a failure mode	The navigation bar displays the path of the active element and the corresponding fault tree appears in the work area.
	Select a failure mode	If a fault tree is displayed in the work area and if events pointing to this failure mode are displayed in this fault tree, these events are selected with an orange border.
From the navigation bar	Click an element in the path	The element is activated. The architecture tree and work area are refreshed, if needed.
From the fault tree	Click the symbol of a basic event	Navigates into the basic event and the navigation bar is updated.
From the fault tree	Select an event	A blue border appears around the selected event. If the event points to a failure mode, it is also selected in the architecture tree.

Note: Double-clicking an element in the fault tree, lets you rename the associated failure mode.
