[PyMOL] Showing the surface

Hi,

I want to show the electrostatic potential surface 10A away from a
protein.  I used to do this by setting all of the vdw radii to 10A,
but I'm wondering if there's a better way these days.  The surface I
got by altering the vdw radii always looked really choppy and not so
smooth.

Thank you,
