Hi, I’m trying to run this script for Cell Size selector in butterfly but I get this error and don’t know how to fix it, i need to run it form a geometry built in GH to repeat the process modifying the geometry

import rhinoscriptsyntax as rs

import Rhino.Geometry as rg

import math

bBox = _geo.GetBoundingBox(True)

Box = rg.Box(bBox)

dim = Box.X.Length

if Box.Y.Length < dim:

dim = Box.Y.Length

base = 10

n = math.sqrt(2)

def quality(x):

return {

0 : base,

1 : base * n,

2 : base * n * n,

3 : base * n * n * n,

4 : base * n * n * n * n

}.get(x,10)

div = quality(*quality)
size = dim / div
cellSize* = format(size, ‘.2f’ )
