Creating Diagrams for a subset of objects in the Ecore Model [message #929535]

Hi,

I have an Ecore file which has more than 100 EClasses. Now, I want to create a diagram only with a subset of objects(Max 5). Just wanted to know what would be the easiest way to do that.

The problem is, whenever you create a Diagram, in the dialog, you can only select the EPackage and not a list of EClasses under the package, and so it creates the diagram with all the EClasses in that package.

I don't want to generate the complete diagram and filter the rest of the objects Razz

.

Thanks,
Ranjith

You may know this, but in case it helps here are two key things to note that I missed at first:

You can have multiple diagrams in a single ecorediag. For some reason diagrams are a bit hidden in the outline so they are hard to miss- they are under the top-level package and after all the elements.

You can add drag elements from the outline onto the canvas.

So to create a diagram with just a few elements I would do the following:
"Initialize Ecore Diagram" from the ecore normally
Then select the package in the outline and choose "New Digram"
Then select the elements you want and drag them on to the diagram

I do the above steps all the time when exploring the model with "Navigate > Restore Related Elements" to explore a subset of elements.

Glad to be of help. As long as I am sharing, be sure to check out the New_and_Noteworthy. That seems to be "the documentation" for EMF Tools Diagrams. I updated the wiki to make that more clear, but since you have been using it for a while you have missed it as I did at first.

Hi!

I have a follow up question about this. The drag and drop to new ecorediagram works fine, but the problem is all the elements don't reflect in its ecore which I need for later GMF. So is there a way to synchronize the changes to ecore or create a new ecore based on this diagram? Any hint is appreciated.

Could you be more specific or send sample model to reproduce your problem ? It should work fine as there is no "synchronization" involved, the diagram editor directly changes the Ecore model instances.
