Only one realized interface messages in sequence diagram?

Is it possible to have one class (Class1) realize 2 different interfaces (Int2, Int3) where different classes require each interface (Class2-Int2, Class3-Int3) and only the operations associated with one interface (say Int2) show up in a sequence diagram when drawing a message between Class2->Class1 (for example).
I’m not using VP-UML for programming so this may not make sense from that perspective. I’m trying to use it for system modeling.


Hi bukkatee,

Thank you for your post. I have prepared a video to show you how to create a class that realize interfaces, and how to create lifeline from class. Please watch at:

I hope this can help you out. If not, please feel free to give me a reply.

Best regards,
