Start to Interactively create MSG-flow for 'Airport-Diagrams'
You are about to start a Message Diagram using interactive choices. The choices can be found on the right. The initial choice (#0) is to generate this for Airport-Diagrams: 'A passenger arrives at the airport who wants to board an airplane.'. On right you will see the new choices appear once a choice is made. You can also change choice #0 to start from different entity or flow. The next choice (#1) to be made for Air-Passenger is to decide on the following: Ticket-valid or Ticket-invalid.
During the process of making choices the ASCII formated MSG-Flow will be drawn. It is possible that you need to make more choices to see the first visible results. Once the message flow is finalized a graphical representation will be created. As well as a textual reprensentation usable for some free tools.
