The "fit model in map" and "fit map in map" tools (menu Tools / Volume
Data) report the relative translation and rotation of two models. But
if you are not doing a fit I don't know of an easy way to get that
information. There is the "matrixget" command that writes rotation and
translation matrices (3 by 4 matrix) for each model but that would
require some calculation to extract a rotation angle and translation.
Do you want the relative orientation between two models, or just the
absolute orientation of a single model on the screen? What center of
rotation do you want? If you choose a different center of rotation then
the displacement is different.
A pretty simple Python script could give the desired information.
I've attached an example script that you can open in Chimera (use File /
Open) to report the relative position of two models.
