Association class


I want to create an association class between two classes but when I select this tool it doesn’t work. Can you help me?

Hi All,

I use VP UML every now and then when I need to deal with UML diagrams. It is a great tool, but it seems silly that every time when it comes to an association class I can’t remember how it is drawn. Therefore, I have visited this page for many times during the last couple of years.

I think the development team can simplify it a bit.


Dear Bahman,

Thank you for your suggestion and we sure will consider about this.

Is it possible to create an instance of an AssociationClass, and display the link to the corresopnding association?

I could get an instance of an AssociationClass by creating an “Instance Specification” and adding the corresponding AssociationClass classifier. But I could not get the link displayed. (See bottom note in the image)

I can neither show the name of an instanciated association, even if I specify the corresponding classifier. (See top note in the image)
