  I created the 2D schematic shown below and use the left side as the axis to apply VROTAT and got the geometry shown in the second plot.
  
  After VROTAT, I cannot choose individual volumes using Cylindrical coordinates. Volume 1 and 2 stay together and volume 3 and 4 stay together. No matter whether I set the radius as volume 1 or volume 2, it will select both 1 and 2. The same for 3 and 4...

  The code is attached. How to decide the offset value? Is there a rule?
  For example, to select 1+2, 'VSEL,S,LOC,X,0,B-S_offset*8' works but 'VSEL,S,LOC,X,0,B-S_offset*7' didn't work.
