Questions about use case diagram on EA 12
« on: June 24, 2015, 12:56:54 am »
Hello,
I have been creating a use case diagram using the SysML 1.3 profile in EA version 12. If I drag an actor from the Library package the stick figure has a blue head. However if I drag an actor onto the diagram from the Toolbox I get an orange head even if I use the Advanced, Instance Classifier menu to specify the classifier. What is the significance of the different colours?

I also have a second question. When I drag a Communication Path line from an actor to a use case, I get an arrow head. On a previous model it was just a line with no arrow heads. Does anybody know why this might be happening?

Thanks in advance.
Richard

So I am going to answer my own question!

The blue colour indicates an Instance rather than a Link.

The arrow heads were caused by the Links Option, "Association Default = source->target" being checked.
