Opening an Existing Project for UML Modeling

You can add modeling capabilities to an existing implementation project that was created without UML modeling.

When you open a project subdirectory from the Model View or Diagram View, UML modeling reverse engineers the contents into a namespace diagram that shows the namespaces, classes, and interfaces and their interrelationships.

To open an existing implementation project for modeling:

Make sure that UML modeling support is activated.
On the main menu, choose FileOpen Project.
In the Open Project dialog box, specify the project location.
Select the project or project group file.
Click OK.

Result: With UML modeling support activated, opening existing implementation project automatically reverse engineers the existing source code into class diagrams.
