To show the messages that pass between the lifelines in
a communication diagram, you must begin by creating a message pathway.
Before you begin
You must have a communication diagram open that contains at
least two lifelines.
Procedure
- In the Palette, click Message
Pathway.
- In the diagram editor, click one lifeline and drag the
cursor to the second lifeline.
Results
The two lifelines are connected by a solid line to which you
can now add messages.
