Greg,
You can also use the alter command to change the vdw to the value you want.
This is often done with SAXS bead models so that they can then be surfaced.
alter (n. ca), vdw= 3
If this is set after the show spheres command the rebuild the view
rebuild
Hope this helps.
Best regards,
Mark

Hi Greg -
If I understand correctly (and just on a quick visual inspection in PyMOL it
looks like I'm at least close), the sphere_scale setting will scale the size of
the sphere relative to the van der Waals radius of the atom
