Hi all,<div>I am trying to colour with coulombing potential only a portion of the surface I generated, and show it together with the rest of the surface, coloured in grey.</div><div>The way I&#39;ve done it is to create a duplicate of the pdb model, generate surface1 from the full model, and surface2 from the selected area, and colour with coulombic potential only surface2.</div>

<div>The issue is that sometimes surface1 is &quot;in front&quot; of surface2, and the only way to see surface2 is to hide surface1. This is not related to the order I create the surfaces apparently, but rather to the order I created the models.</div>

<div><br></div><div>Is there a way to &quot;bring to front&quot; or &quot; send to back&quot; surfaces or models for display purposes, rather than copying models (and re-doing the selection for the residues that I want coloured?).</div>

<div>Or a way to colour with potential only the selected area of a surface?</div><div><br></div><div>Thanks!</div><div><br></div><div>Giulia</div>
