[Chimera-users] Fit in map equivalent for surfaces?

The fitting uses the actual map values, although you can delimit them by a surface. So, I’d say there isn’t really a way to use the envelope or surface only, without the interior values. However, you could use “molmap" to simulate density maps from the two atomic structures and then use the map-map fitting.
