Can Arrows be added in RRC Use Cases to indicate directionality?


Brian Vander Mey (5041520) | asked Jun 11 '13, 9:16 a.m.

In the most Basic of Use Cases, arrows or directionality are not needed.  But they are required to demonstrate generalizations, <<includes>>, and <<extends>> (and <<communicates>> and <<uses>> etc). 

See pages 76, 77, and 86 of this UML guide on use cases: http://www.omg.org/news/meetings/workshops/presentations/uml2001_presentations/01-1_Kobryn_Structural_and_Use_Case_modelingTutorial.pdf

How is this accomplished in RRC?  I'm only able to draw straight lines, just associations.

Should I understand from the work item that the current development cycle is working on enhancing modeling in RRC?    Use Cases was the only modeling type that was even a little close to what we need.  Its all there except for the directionalities.  But other model types (Context Diagrams, Event Diagrams, Data Flow Diagrams, etc.) are not doable at all currently.
