To create relationships between selected elements
The Active Selection area shows the elements currently selected in the active diagram, table, matrix, map, or Model Browser. It changes with each click of the different elements of when you switch to another diagram.
To choose one or several elements at a time, do one of the following
The multiple selection works in one area at a time. For example, diagram pane, table, matrix, relation map, or Model Browser. If you need to select elements from several locations, you need to pin your current selection.
The Pinned Selection area show the elements you choose to pin from the Active Selection. This is needed when you want to select elements from different locations (for example, you need to select elements from different diagrams, or from the diagram and Model Browser). In this case, you should pin each selection.

When the relationship is created, you can visually identify its direction (source and target elements) under the Containment tree > Relations.
