Your project can have a binary library whose content you may want to display in your diagrams. For example, you can show entities that reside in the MSCorLib.dll or other project references. Such resources exist for the project, but UML modeling does not include them in the generated HTML documentation for the project. 

The Model View enables you to view class diagrams for references included in your projects. You can add references to your project using the Project Manager.

1. In the Project Manager, expand the desired project node.
2. Right-click the Requires node, and choose Add Reference. from the context menu.
   Tip: Alternatively, choose Project->Add to Project
   , and then click the Requires tab on the Add dialog box.
3. In the Projects tab, select the projects to be referenced and click Select.
4. Click OK when ready.

Result: The Choose Type to Instantiate dialog box shows all referenced projects, making it possible to choose the desired classifiers from the different projects.

1. Open or create a class diagram.
2. Right-click the diagram background and choose AddShortcuts. The Edit Shortcuts dialog box opens and displays the content available for the diagram and all content residing outside of the current namespace.
