Hi Yorick, That is an annoying problem. I fixed a bug in ChimeraX that caused the rotation axis to change when a part of your structure passes in front and 3d labels are being shown. That fix is in the ChimeraX daily build. In your case are there 3d labels shown? If so get the ChimeraX daily build to fix the problem. The default rotation center mode in ChimeraX is called "front center" -- it tries to rotate about the frontmost atoms/ribbon/surface visible in the center of of your graphics window. But it only is supposed to check which objects are in the center when you translate the the scene. If you do a mouse rotation, then another rotation, then another, it should keep the rotation center the same. There are other rotation center modes you may prefer. See the ChimeraX cofr (center of rotation) command. https://www.cgl.ucsf.edu/chimerax/docs/user/commands/cofr.html For example there is a Pivot mouse mode in the "Right mouse" toolbar that sets a fixed center of rotation point on the atom you click using the right mouse button (or Command-click on Mac).

Hello,
In my work with ChimeraX I have to rotate my proteins quite a lot to get a good look at different residues and helices. My problem is that very often when I am rotating my protein using the left mouse button, another piece of my protein will glide across my screen in the foreground, at which point the axis of rotation will lock onto this other piece. Is there a way to disable this unwanted locking? I am fine with these pieces floating across the foreground, as long as my axis of rotation doesn’t suddenly lock onto them. I want the rotational axis to stay where it was when I started rotating. I look forward to your reply on how to fix this issue. Thank you in advance.
With kind regards, Yorick van Hazendonk _______________________________________________ ChimeraX-users mailing list -- chimerax-users@cgl.ucsf.edu <mailto:chimerax-users@cgl.ucsf.edu> To unsubscribe send an email to chimerax-users-leave@cgl.ucsf.edu <mailto:chimerax-users-leave@cgl.ucsf.edu> Archives: https://mail.cgl.ucsf.edu/mailman/archives/list/chimerax-users@cgl.ucsf.edu/
