Object instances

[dkunzman]

Hi -

I am creating a sequence diagram with EA 7.0.818 and would like to create an object instance.  for example I would like to create a instance of the object student named "sparks".  How would you do that?  According to UML 2.0 the object instance should have an underline like sparks::student.  Any ideas?

thanks, doug

Go to the project browser and hit the new element button or right-click and select ADD->Add new element. Name it "student" (make sure element type is set to "class" - I think this is the default). Then, with your sequence diagram open, click on your student class and drag to the diagram and drop. Select "as instance of element (object)" and name it "sparks". that should do it?
I believe the underlining notation only applies to class diagrams and not interactions such as sequence diagrams.

Yes, object names should be underlined, except when they are at the head of a lifeline on a sequence diagram. I don't think it is explicitly stated in the spec, but every example sequence diagram in the UML 2.1.1 Superstructure shows the name not underlined.
