Transform a class on itself

[Tom G]

Is there a way I can transform a class on itself: the transformation should not create a new class element but adapt/replace the class element it is transforming without losing information or breaking relationships...

I would like to do this to automatically add a bunch of tagged values to the attributes of the class. Is there another way I could/should do this (without using the automation interface) ?

Thanks.
Tom

The only way that comes to my mind would be an add-in. Or you would need to delete the source class manually after transformation.
