@matterhorn103 Briefly I thought your line of argumentation were to offer a supplementary style of representation of a unit cell, i.e. not only the one with “full spheres”
regardless if they are within the parallelepiped and count 1/1, on a face (1/2), ridge/arête (1/4), or apex (1/8), but capped
If one of the atoms “happens” to be at (0,0,0) either a) because the asymmetric unit defines them at this spot, or b) by filling the unit cell (i.e., asymmetric unit + application of the symmetry operators of the unit cell) I presumed the origin of the coordinate about the enveloping “shoe box” (where \vec{a}, \vec{b}, \vec{c} in the display of CCDC’s Mercury, or here Jmol “emerge”) would automatically recenter and realign.
The .cif read for the static/dynamic visualization is plain NaCl COD 1000041.
The commands issued to Jmol after downloading the .cif were
