Creating execution specifications manually

In sequence diagrams, an execution specification is created automatically when you create a synchronous or an asynchronous message on a lifeline. You can also manually create an execution specification to show the start and finish behavior in an interaction.
You must have a sequence diagram open that contains lifelines and messages.
To create an execution specification manually:
  1. In the Palette, click Execution Occurrence.
  2. Click the target lifeline at a position that does not have an existing execution specification.

If you want to delete an execution specification, it cannot have a return message.

Note: To create a nested execution specification, click the target lifeline at a position that has an existing execution specification.
