Users can create a Hierarchy Diagram (HID) to show the relationships for any item in a project. This can be very helpful when reviewing the potential impact of a desired change to an item. When an item is selected you can create the diagram by right clicking and choosing Hierarchy Diagram under the Links option or by clicking the HID button on the home tab.
The resulting diagram will show items linked to the original selection. By default a HID shows bidirectional links three layers deep and for all item types.
The Control section on the left provides general statistics and is where adjustments can be made. The HID properties button opens an option window with two tabs: Options and Item Attributes. The Options tab sets the general layout and details such as how many layers to show when initially drawing a HID.
The Item Attributes tab allows you to customise what is shown in each box on the HID.
Below this section in the Cross Reference area one can define a subset of the HID data of interest. If you only wish to include certain item types, link types, direction, owner or instance it can be selected here.
Within the diagram itself, a number of things may be adjusted to help better understand the data. Right clicking on an item in the diagram presents options to review details of the item and its links, expand or collapse the portion of the HID in relation to that item and even redraw the HID with the selected item as the source.
