My class has been using VP 4 UML Standard edition 6.1. I have installed it on a common share which all students can access. Within the last 2-3 weeks they are no longer able to drag & drop the association class in the Class Diagramming tool.
In attempting to fix this I seem to have now disabled the ability to drag & drop associations. However, classes can still be associated by clicking on the class and associating it with another class.
I just noticed another issue, when I click on a class it automatically creates a unary association (the class to itself).
What have I done???
Thanks for your message. May I know what is your steps to create the association class?
I too am finding this - if I draw 2 classes, select them both and then drag from association class on the tool bar and drop on one of the classes, nothing happens.
I can’t draw an association class on it’s own either.
Ah ha - I believe these are the steps required.
- Draw class1
- Draw class2
- Associate class1 and class2 with a solid line
- Draw class3
- Click Association Class
- Draw line from class3 to the line associate class1 & class2
- Note that the resulting line is dotted denoting an association class
This could be a misunderstanding. The presentation of Association Class is really a dotted line connecting from association to Class. It isn’t a concrete shape like Class.
If there’s anything else I can help you with please let me know.
