Ok so the same workaround does work in ChimeraX (I didn’t read the docs carefully enough…) so as an alias to crop all maps in a 15 Å sphere around the center of rotation, this does the trick: "alias map_sphere_15 surface unzone ##~num_residues; sel; marker #10000 position cofr; sel ~sel; surface zone ##~num_residues nearAtoms sel distance 15; close #10000"

Hi,
Surface zone allows one to carve the map in a sphere around a selected atom (with “nearAtoms”).
When navigating around the map, it would be convenient to be able to use the center of rotation as a reference point instead.
Would it be possible at some point to add a “nearCofR” option to surface zone to facilitate this?
In Chimera, I had kind of a hack-y way to do this, by placing a marker atom at the center of rotation and using that as the reference, but this option is not yet available in ChimeraX.
