The Relationships Window

If you want a quick overview of all the relationships of a single element, you can obtain this from the Relationships window. This window lists all the relationships of the element currently selected in a diagram or the Project Browser, showing:

The relationship type
Any stereotype on the relationship
The source and target elements in the relationship (the selected element can be either one in the relationship)
The direction of the relationship
Any stereotype on the related element
The related element type
The roles, if defined, of the target and source elements in the relationship

 

The Relationships window also has a Target in Diagram column which, if the row contains the value Yes, indicates that the related element is visible in the currently open diagram. If the related element is not in the current diagram (the row has no value), you have the option of adding it.

Add Related element to current diagram

Right-click on the item line and select the Place Related Element in Diagram context menu option. The cursor changes to the 'drop element' symbols (small rectangle and arrow with a boxed plus sign); move the cursor to the point in the diagram at which to drop the related element, and click the mouse button.

This facility is useful in building up a picture of how an element interacts with the rest of the model, especially when reverse engineering an existing code base.

 

 

Notes

In the Corporate, Business and Software Engineering, Systems Engineering and Ultimate editions, with security set ON, the diagram and the source and target elements must be free for editing before these options are available for use
Adding a related element from the Relationships window to the diagram does not change the focus of the window to that related element; the originally-selected element (and the original subject of the Relationships window) remains in context, and you continue working with that element..
