The reason that pressing the Fit button on the Fit Models in Maps dialog
is not doing anything is because you have no atoms selected. A warning
about this that says "No atoms selected" appears in the dialog. The fit
only applies to models with selected atoms because that allows you to
fit one PDB model at a time when you have multiple ones opened.
The fit tool only does a local optimization -- relatively small rigid
rotations and shifts -- so you have to first move the PDB model by hand
to approximately where you want it.
How to do this is described in the Guide to Volume Data Display:
