I'm using MEGA 2009 sp5 cp11. I want to create a communication diagram but i don't find where it's possible. I have try it from an interaction, but only one diagram is available : Interaction Definition Diagram. While it's stated in the "MEGA for UML" documentation that the sequence diagram, communication diagram and interaction overview diagram are created from an interaction.
So my questions are :
From which object can i create a communication diagram ?
Does it need special authorization to create this type of diagram ?
