[chimerax-users] [Chimera-users] zoom on the selection after orientation of the selected object

[Elaine Meng]

Please send ChimeraX questions to Chimerax-users at cgl.ucsf.edu instead of chimera-users at cgl.ucsf.edu to avoid confusing people between the two programs.

The view command sets clipping planes, and my guess is that when you zoom, the clipping planes don't adjust accordingly (actually I think that may be a bug, will check with the other developers). 

At least in my test case, the way to avoid this is to put "clip false" in your view command, e.g.

view #1.1 orient clip false; turn z 90

I hope this helps,
Elaine
