Dear all!

I am currently facing the problem of rendering a lot of systems in an orthographic representation.
Examples are snapshots in time of a lipid bilayer simulation.

To get a more quantitative view of processes happening at the lipid bilayer, I would like to add a
ruler/frame to the system. I know that there exist the “Ruler” extensions in VMD. However, this
ruler only shows me relative length scales and not the absolute limits of my current view. One
workaround would also be extracting the limits of the atomic positions in my current view and
plotting the frame with an external library after the render process.

Thanks for your help!
