When I drag a class into the diagram not all the associations are shown.
I would like to see associations that I have already created though another diagram but I cannot find a way to do this.
Product: Astah Professional
Sorry, it is Astah Community 7.0.0, not Astah Professional
With Astah Professional, you can do this, but Astah Community does not support this feature.
You can try out Astah Professional for 50 days for free. So give it a try. :)
[In Astah Professional]
Right-click on a model in diagram and select [Show Related Elements] on the pop-up menu.
All the related models appear on the diagram.
