Paneling tool restores trimmed surface with undesired results/

I’ve created a surface which required trimming. Now, when I apply the paneling plug-in to create a grid on the surface, the grid extends to restore the trimmed portion of the surface. How do I disassociate the vestige/legacy of the trimmed portion of surface? Any thoughts?

No experience with the Paneling Tool but I suppose you could shrink your trimmed surface to get rid of the underlying legacy portion.

Paneling tools use the UV grid of the untrimmed surface to create the panels. You will get closer to, if you shrink the trimmed surface but generally, you will have to figure out how to handle trimmed borders yourself.
