There are two different types of association possible between items and diagrams:
• parent-child associations.
• user-defined associations, allowing you to associate any dictionary item with any method.
Where permitted, you can create links between items in the dictionary and diagrams. You can use this feature when a diagram describes a dictionary item, for example Sequence Diagrams describe use cases.
The following types of dictionary items can be parents of diagrams:
Activity
Activity Diagram
Atomic State
State Diagram
Class
Composite Structure Diagram

Text Diagram
Use Case Diagram
Data Type
Composite Structure Diagram
Sequence Diagram

You can create a diagram from the dictionary item context menu. In the case of State Diagrams and Activity Diagrams, this is the only way that you can create them, because a State Diagram must have a State Machine as a parent and an Activity Diagram must have an Activity as a parent.
To create a diagram from a parent dictionary item:
1. In an appropriate pane, right-click the parent dictionary item.
2. Point to New, and then click the required diagram type.
