Hi Daniel, Yes, often more than one isosurface is shown for a given map, and besides or as an alternative to making the outer one transparent, you can use the mesh style. The Volume Viewer tool's context menu (shown with right-click, except on Mac Ctrl-click) includes choices to add or delete thresholds, i.e. contour levels. <http://rbvi.ucsf.edu/chimerax/docs/user/tools/volumeviewer.html> Or it can be done with commands, as in the first example in the "volume" command documentation: <http://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html> volume #1 style mesh level 0.8 color red level 1.2 color 0,50,80 I hope this helps, Elaine ----- Elaine C.

Is it possible to visualize two surfaces for the same model? I was thinking for example for the purpose of showing two different levels of a map with the lower one as a semi-transparent surface. The work-around is to load the same map twice into two different models, but that will take up more memory and is more cumbersome. Regards, Daniel
