I have a session file that contains everything I need to make figures for a paper.  With pymol, I saved the get_view matrix in a text file for each view which meant that with one session file I could easily recreate the views if I needed to go back and tweak a figure.  In ChimeraX, the closest way that I found to replicate this was to use named views.  Am happy to supply a session file if it helps also happy to be educated if there is a better way of doing this, especially as now the ChimeraX session files can get rather large.

Cheers
