Adding existing links to a package diagram (UML Standard profile)
You can add existing links to a Package Diagram through the populate commands and through the diagram's toolbar buttons.

To add missing relationships relating to a diagram item:
• On a Package Diagram, right-click the item, point to Populate, point to Links, and then click the command for the relationship you want to add.
Note that Access, Import, Package Merge, Profile Application and Realization relationships are all added through the Dependencies command.
To add an existing access or import relationship:
1. On the diagram's toolbar, click the Access or Import button.
2. Click the relationship's start item - a Model Representation, Package, Profile Representation or View.
3. Click the relationship's end item - a Model Representation, Package, Profile Representation, Model Library, Viewpoint or View.
4. From the context menu, click the command for the Access or Import relationship you want to add.
