Creating clipping plane from Grasshopper?

after I restarted Rhino, it messed up my script :smiley:
I have to create it from scratch following the same step-by-step scenario.

  1. creating the clipping plane with ghpython
  2. OK
  3. add sticky with value clipping plane guid
  4. a = sticky (to create the clipping plane from the sticky)
  5. add in front of all a line to delete the clipping plane with guid that is equal to the sticky.
