Hi @travis.designer.vn
First purge the history from your grid (to prevent it from following the surface in the next step). Now use ExtendSrf to increase the width of your band (both upper and lower edge), so that the surface extends a little past your grid. Now do the panelling again, and you will have the full circles.
