Creating or opening a diagram
Creating
a diagram
Several model elements can own associated diagrams, and these diagrams
can all be created through the corresponding icons in the explorer icon
palette.
The diagram creation process is identical for all diagram types,
although not all diagram types can be created for all model elements (please
see the table in "Introducing Objecteering diagrams").
The figure below illustrates the creation of a class diagram.

Opening
a diagram
When a new diagram is created, it is automatically opened in the work view window.
To open an existing diagram, you can simply double-click on the diagram
in the Objecteering explorer.
If you try to open a diagram that is already open, the diagram in
question is brought to the foreground in the work view window.
