You can provide more detail about a model element, such
as a package, component, or state machine, by creating a diagram
in it. You can create several diagrams of different types in a single
model element.
The types of diagrams that you can create in a
model element depend on the type of model element that you select.
For example, you can add only class, collaboration, and sequence
diagrams to a collaboration; however, you can add all diagram types
to a package.
To create a diagram in a model element, in the
diagram editor, right-click a model element; then click Add Diagram and
click a diagram type.
The diagram is added under the corresponding model element
in the
Model Explorer view, and a blank diagram
opens in the diagram editor.
Tip: You can also create
a diagram in a model element in the Model Explorer view.
