The "turn" command allows you to specify rotation axis, center of rotation, and magnitude of rotation (degrees). Axis and center can each be given as a vector. Turn performs a rotation relative to the current position, but you can first orient the volume so it is aligned with the "laboratory" frame of reference, using either the "Orient" button on Volume Viewer, or the command "reset" without arguments. The laboratory frame of reference is:
X horizontal in plane of screen, increasing rightward
Y vertical in plane of screen, increasing upward
Z normal to screen, increasing toward viewer
You can show the command line by choosing it from the Favorites menu in the main Chimera window.
I hope this helps,
