[chimerax-users] session file sizes

[Tom Goddard]

To close molecular surfaces

	surface close #1

or just

	surf close

If instead you do

	~surface

that hides the surface.  I discourage use of these obscure "~" commands that Chimera used.  Use "surface hide #1" or "surface close #1".

If you just hide the surfaces they are still in the session file.  You can also see the surface models in Model Panel by clicking the little triangle and the left of the model name to show submodel of your molecule.  And you can choose those surface models and close them.

I have considered not saving the molecular surfaces and just recomputing them although that will make restoring the session slower as it tries to recompute the surface.
