Chapter 5 Building Dynamic Diagrams

Creating a communication diagram from a sequence diagram

You can create a communication diagram from a sequence diagram. The new communication diagram reuses the objects and messages from the sequence diagram, and creates instance links between the objects that communicate using messages. The conversion also updates any message sequence numbers, based upon the relative position of messages on the timeline.

Note that when you create a communication diagram from a sequence diagram, the two do not remain synchronized – changes made in one diagram will not be reflected in the other.

To create a communication diagram from a sequence diagram:

1. Right-click in the background of the sequence diagram and select Create Default Communication Diagram in the contextual menu.
   
   or
   
   Select Tools→Create Default Communication Diagram.
