However, I did not have this problem with transformed atomic coordinates. Tested in UCSF ChimeraX version: 1.7.dev202304130132 (2023-04-13) Reported by Kevin, email address in the Cc list of this ticket.

The receptor is the same in all cases, just the ligand bound in the binding pocket varies. I want to show a directionality to how the ligands are binding in the pocket between the structures, so I have aligned the maps and models together and am attempting to run ""measure center"" and ""measure inertia"" to initiate this comparison. However, when I run these commands, the output markers and ellipsoids are not positioned in an aligned fashion as their parent objects, but rather in there initial positions before alignment, which is not useful for comparisons of the subtle movements between structures.
