Randomise grids on curtain wall from list of spacing values

Revit

There might be a more elegant solution than this but it seems to do the trick…

Python script:

import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *

import sys
#The inputs to this node will be stored as a list in the IN variables.
pyt_path = r'C:\Program Files (x86)\IronPython 2.7\Lib'
sys.path.append(pyt_path)
import random

#The inputs to this node will be stored as a list in the IN variables.
vals = IN[0]
length = IN[1]
refresh = IN[2]

def addVals(nums,total):
	sum = 0
	vals = []
	i = 0
	while sum<=total:
		i = random.choice(nums)
		vals.append(i)
		sum+=i
	return vals

OUT = addVals(vals,length)

Code Block:

vals = DSCore.List.RemoveItemAtIndex(list, (Count(list)-1));
amount = DSCore.List.Count(vals);
seq = 1..#amount..1;
spaces = Math.Sum(DSCore.List.TakeItems(vals,seq));
params = spaces/length;
points = (curtWall.GetLocation()).PointAtParameter(params);

EDIT to add, I’d freeze the CurtainGrid.AddGridLineByPoint node and run a few times refreshing, until I see a combination of points I like. And follow this suggestion from the post you linked above:
