@wim thanks for posting the dialog screenshot.
The problem is with the AutoCPlane.py file. The top of the file looks like this:
import rhinoscript.userinterface
import rhinoscript.geometry
import Rhino
import scriptcontext
import System
import math
import time
import rhinoscriptsyntax as rs
The last import normally loads all the modules and all functions are associated with the “rs” alias but since the userinterface and geometry modules have already been loaded in the 1st 2 lines they won’t be reloaded and the functions from these modules won’t be associated with “rs”. That’s why “rs.GetInteger” on line 250 fails. Delete the 1st 2 imports and then reset the python engine and everything should work.
Let me know how this works out.
