In modeling diagrams, you can define aliases for diagram elements.
You can then choose to show or hide the aliases.
Specifying aliases for diagram elements
In modeling diagrams, you can specify aliases for the diagram elements.
Aliases are useful when you want the diagram element to have a name that is
different from the name that is displayed in the Model Explorer view.
Showing aliases in diagrams
In modeling diagrams, you can show or hide the aliases that you specify for diagram elements. The display mode is controlled at the diagram level, which means that you can display the aliases or the real names of the diagram elements for each diagram.
