The Hierarchy Browser presents model elements in a hierarchical tree view, with elements arranged according to their containment relationships. This view is similar to what you might see in a file browser. The Hierarchy Browser does not show the actual relationships as elements; instead, it shows only the source and destination model elements, arranged hierarchically from parent to child. The Hierarchy Browser is particularly useful for browsing and editing nested elements such as Publication elements. (See Publishing models for more information.
There are two ways to open a Hierarchy Browser:
The Hierarchy Browser has two panes; they can be arranged either vertically or horizontally, depending upon the settings on the Browser page in the system settings (see System settings for more information). The first pane (either top or left) shows the hierarchical tree view of model elements. The top-level element is the element you selected before opening the Path Browser; if you opened the browser from the Transcript window, all of the existing models are listed as top-level elements.
If an element has any important relationships to other elements (such as containment, conformance, or collaboration), a plus sign (+) appears beside the element in the list. Click on the + to expand the list and see the related elements. If an element is linked to by multiple others, it might appear multiple times in the list.
