New Association 

The New Association command, accessed from the diagram Toolbox, allows you to create new associations for the current component.

 

The command prompts you for either bidirectional or unidirectional associations.

 

 

A new UMLAssociation is added to the start of the relation for the target entity and a new Component is created and added to the ends of the relation for the UMLAssociation. Also, the following attributes are set for the UMLAssociation: Type is set to Association, Directionality is set to either bidirectional or unidirectional.
