[Chimera-users] Regarding adding plane surfaces....

Hi Chinmaya,

   You can use the "shape rectangle" command to make planes.  In the 
attached image I made the two planes with

     shape rect width 100 height 100 slab .1 color .7,.7,.7,.2 center 
0,0,-50 coord #0
     shape rect width 100 height 100 slab .1 color .7,.7,.7,.2 center 
0,0,50 coord #0

Since I wanted the planes aligned with volume #0 I specified the "coord 
#0" option.

If you had atoms to start with, for example if you made the volume from atoms using the command "molmap", you could go back to those atoms use them to define planes.  It could be done with the "define" command or "Axes/Planes/Centroids" (under Tools... Structure Analysis).
