Adding existing classes to ecorediagram

Question

I want to edit my ecore model in a diagram. I created an ecorediag but I cannot find any way to add the existing classes in it. The only way it works is if I use the "Initialize the diagram with existing domain model objects". But if I create new classes or accidentally remove them, there is no way I could add them again.

Answer 1

You can drag & drop existing elements to the diagram from the Outline view.

Answer 2

Smth's obviously not working right for you because that should be reasonably easy. Two options I'm aware of:

1. If you reveal the palette (it might be collapsed to a little triangle in the top-left hand corner of your ecorediag), the EClass icon (2nd from top) lets you create a new EClass by drag-dropping it onto the diagram.
2. If this isn't working for some obscure reason, you could go to the ecore model linked to your diagram, right-click an EPackage and select New Child->EClass. That new class can then be dragged & dropped onto your diagram.

Hope this helps; let me know if not.
