The hierarchy chart depicts the connections between various layers of elements. There is no certain pre-defined semantic for a hierarchy in a traditional representation, allowing the user to define the specific set of relationships to deliver the desired presentation and insight. Views of the functional, physical, and traceability hierarchy are examples of how they can be used. Hierarchy diagrams are available for all elements in the general representation set. When an element and a hierarchy definition are combined, a hierarchy Chart is opened. The element specifies the diagram's starting point. The hierarchy definition specifies the relations (and optionally target classes) that will be traversed when creating the hierarchy diagram. CORE constructs the graph by beginning with the top-level element and checking if any specified relationships have targets.
