Generating a Sequence Diagram from an Activity Chart

A sequence diagram can be created manually before an activity chart has been created, or automatically from an activity chart. You can save time by generating a sequence diagram template from the activity chart. A sequence diagram template generated in this manner contains all the lifelines for each activity. However, you must enter and label the message lines and other notations manually.

Note: Generating a sequence diagram from an activity chart creates only an initial template; subsequent changes in the activity chart are not automatically updated in the sequence diagram.

To generate a sequence diagram template from an activity chart:

1.
2.
Select the main activity. If a subactivity is selected, the generated sequence diagram contains only activities within the selected sub-activity chart. External lifelines are created for activities that are connected to (or into) the selected activity.
3.
Select File > Create Sequence Diagram.
4.
The sequence diagram opens, as shown in the following figure, having all the activities and external activities of the selected activity chart. The messages, however are not created.
