Hi Stefan, In the Volume dialog Data Display Options panel you can turn on "Show outline box" to draw lines around the currently chosen volume (the one with name highlighted in the volume dialog). It doesn't label the axes. The following message describes how to show red,green,blue arrows for axes similar to the program VMD. http://www.cgl.ucsf.edu/pipermail/chimera-users/2006-April/000761.html Tom

Hi.

It is possible to show the box of a volume, and I wonder if it is possible to show the X, Y and Z axis as lines ?

Best,
