Single is the Default Setup when Hiearchy Tab is chosen (Top Level Only)
Selecting Hierachy to "All" or "Other" Levels
Choosing All opens the model all the way down (Not normally correct)
Choosing Other allow choosing by number of levels down (1,2 - N) (Also Not normally correct)
Selecting Hierachy to Replacement Level
Clicking on a Folder will open or close a level.
The Correct Selection is opening the model to the Replacement level. Shown here the ECU folder has been closed because the ECU is the replacement item when there is any failure within it. All other elements are isolatied to the component level.
