Linking sequence diagram,

[Pradeep bhatt]

Is is fine to link a sequence diagram to another by attaching a note- "The flow continues in another sequence diagram"
Thanks

[Tiago Fernandez]

Pradeep,
I don't think so, cause the sequence diagrams don't have to represent the entire system flow. Think about this kind of diagram like pictures from the parts of the project, and you gotta to abstract a lot!
Best regards,

Why do you feel the need to do so? What harm could be done if you did so? What would be the alternative?

I probably wouldn't put steps 1-10 in one diagram and 11-20 in another. I'd try to have one diagram that shows some chunk of action from beginning to end.
I have certainly had a message into an object in one diagram that made that object do something complex enough to deserve another diagram of its own.
Maybe the two diagrams you are thinking about linking are just the details of a higher level process?

  
Diagram: Do Something Complex
   Command      ThingOne     ThingTwo
 ------------ ------------ ------------
      doFirstStep
      +------------>
      doSecondStep
      +------------------------->

Maybe doFirstStep and doSecondStep are both complex enough to have their own diagrams. But they probably shouldn't have to reference each other. If they do, you might have some unhealthy dependencies.
Zat make any sense?

Rule of a thumb:
Your diagram should fit in A4 size paper with max landscape orientation.
yup

Well said, Stan!

A4 Paper! My favorite thing about the Internet is that now users think vertical scrolling is ok and my diagrams can go forever! Bwaaahhh hah hah!

You might want to use a collaboration diagram if the sequence diagram is taking too much horizontal space.

I don't think that the used space should be the deciding factor. You should decide based on wether you want to show the structure of the collaboration or the chronology.
