Surface event to Grasshopper?

So when I experiment with modifying a Rhino surface referenced by Grasshopper, I’d like GH to be notified if the surface has been modified. In the current case when CVs/“grips” are modified. But how can I in the easiest way make a GH component be aware of the modification?

Not quite sure what you mean here? When you edit a referenced Rhino object, GH updates all components downstream of the referencing component automatically. So in effect, GH is notified of any changes to the Rhino surface.

Modifying CVs doesn’t seem to trigger update in GH.
