Hi Luis,
You would need to generate a new map from resampling the fitted map on the grid of the other using "volume resample".  In general you lose some resolution by the resampling, as discussed in the links below.
<http://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#resample>
<http://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#notes>

If map #1 is fitted to #2, you could generate a resampled map with command something like

volume resample #1 onGrid #2

...which would make new map #3 (if that number isn't already in use).  However, you may want to use additional options to the command, which are explained in the links above, e.g. the "spacing" option for finer spacing.

I hope this helps,
Elaine

I know that maps as such do not have location or rotation information, but I want to generate a new map (with a new cube I imagine) which represents the current position and rotation for a given map. I am working with "fitmap (map # 1) inmap (map # 2)" the idea is to generate the new map from the optimized map, to be able to load that new "result" map without the need to perform any other transformation. If this is possible, I wanted to know if you can give me the command list to be able to do it? I already appreciate the attention provided.
