HelLo,

Is there is a way where i can assign a value to a model elements automatically. for instance when I have an element(A) with attribute that reference another model element (B), i need to build the other attributse of elemnt(A) based on some attribute of element (B)...
Can we achieve that through OCL , or I need to modify the generated code ...

This is probably something you want to do in the editor, not directly in
the model. But then again, it sounds a little bit like such other
attributes are derived (should not be modified in a way that's
inconsistent with the reference to B). Is that the case? You can
express the logic for derived attributes using OCL (or with Xcore)...
