Change Aggregation Connector Form

In Enterprise Architect, the default Aggregation relationship is the weak form of the relationship, represented by a hollow diamond. To change the form of an Aggregation connector from weak to strong, follow the steps below.

  1. Right-click on an Aggregation connector to display the context menu.
  2. Select Set Aggregation to Composite. The diamond is shown as filled.


If the connector is already a Strong (Composition) connector, the context menu option changes to Set Aggregation to Shared.
