How to create a custom diagram made of symbols using several existing diagrams? Supporting organization that uses DoDAF 2 template, I could not find a suitable diagram to express AV-1 and AV-2 requirements. From available Mega diagrams I selected "Overview of Business Processes." It accomodated those diagrams and "Interaction Definition Diagram" that is used as SvcV-2 diagram. Mega generates interfaces (links) automatically to associate entities based on unique names of used entities. SV-1 diagram compatible with the above could address significant analythical trends and relationships. Does Mega have a diagram that would lend itself to become a dashboard?
