Message animation

Various message arrows are created for animated sequence diagrams.

Animated sequence diagrams automatically create the following message arrows while the model is executing:

The y-axis of a sequence diagram indicates both flow of time and steps. No scale is given on this axis, but synchronization is maintained.

When you remove an instance line, all messages sent to and from the instance are also removed. Future arrows relating to the removed instance will be associated with the system border, if the diagram has one.

When you add an instance line, messages to or from the newly added instance are displayed only from the moment the line is added. Messages sent or received by an instance before it was added to the diagram are associated with the system border.

Note: Do not create more than one line referring to the same instance. Otherwise, message arrows will connect to only one of these instance lines in an arbitrary manner.

When you quit animation, you can either save or delete animated sequence diagrams that have been generated by the execution. Saving them creates a record of the execution.
