Hi Paul,
It's basically the same in ChimeraX as in Chimera -- there is a Side View tool for interactive clipping-plane position adjustment, as well as various command options to set the detailed depth-cueing parameters.

 In ChimeraX, these options are within the "lighting" command: depthCue, depthCueColor, depthCueStart, depthCueEnd:
