It is possible to set up a cross reference from one element in Enterprise Architect to another. Conversely, you can view existing cross references on an element, using the Hierarchy window.

Set Up a Cross Reference

To set up a cross reference, follow the steps below:

1. In the Project Browser window, locate the target element or diagram (that is, the subject of the cross reference).
2. Open a diagram that contains the element(s) that are to have the currently selected element as a reference.
3. Right-click on the element. The context menu displays.
4. Select the Add custom reference....menu option.
5. In the Set up references dialog, select the checkbox against each element to include in the explorer as a reference.
6. Optionally, in the Comment field, type some text to describe the purpose of the reference.
    
   

Use the Cross Reference

To use the cross reference, follow the steps below:

1. Select an element in a diagram.
2. Select the Element | Custom References menu option. Alternatively, either press [Ctrl]+[J], or right-click on the element and select the Find | Custom References context menu option.
3. The Custom References dialog displays, showing a list of elements that have been set as cross references.
    
   
    
4. You can open a selected element by highlighting it and clicking on the Open button.
5. If you have a diagram cross reference, you can open that diagram.
6. If you have a string of diagram links, click on the Home button to return to the original diagram.
