Hi Edoardo,
I believe you can do this by choosing "box" display from the rightmost pulldown in the Volume Viewer dialog.  See the screenshot attached below.

Volume Viewer dialog settings:

I hope this helps,

Hello,
Could you please tell me how to display fib-sem tomography data as a compact volume that can be navigated by sliding planes? The data consists of a series of frames that I can convert as .mrc volume or .mrcs stack. I attach a snapshot taken from a review that illustrates (middle panel) the visualisation I would like to obtain. The medical-image panel in ChimeraX is very handy however, the “full” option shows the volume while I need to display the planes of each side to slice through them. 
Looking forward to your feedback,
Best wishes,
Edoardo
