The  whole website was down.  It is back up now, try again.  Yes, you would use the "distance" command.

command:
<https://www.cgl.ucsf.edu/chimerax/docs/user/commands/distance.html>

Distances tool:
<https://www.cgl.ucsf.edu/chimerax/docs/user/tools/distances.html>

If you use the Distances tool it will show the commands that it uses in the Log.  Most GUI actions are shown as commands in the Log so that you can see examples of the commands even if you don't look at the help pages.  However, you should look at the help pages because they are written so that we don't have to repeat the same information all the time in email.
