I came across this charm.
But i try to get it to work for multiple Scope Boxes. I think something in the Python needs to be change for that (?). I already fiddled with Levels and such, but it wasn’t that simple 
.
Script for Revit 2024_2.dyn (76.7 KB)
@c.poupin are you able to help?
Best to share a screenshot with what you have and what you’re seeing. If it’s just a matter of going from one scope box to many then you should just need another for loop.
Elevation markers are not “Views Dependent”, so I don’t really understand the request.
Who’s request? @c.poupin
I will post screenshots and the original Python 
tomorrow @Nick_Boyts
this question ↓↓
@c.poupin Sorry, that was a typo. I meant multiple Scope Boxes. Fixed that typo .
try to use zip() function,
Example: adapt this to fit the structure of your input lists.
toggle = IN[0]
lst_points = UnwrapElement(IN[1])
lst_modelPoints = UnwrapElement(IN[2])
lst_cropCurves = UnwrapElement(IN[3])
viewType = UnwrapElement(IN[4])
lst = []
if toggle == True:
TransactionManager.Instance.EnsureInTransaction(doc)
for points, modelPoints, cropCurves in zip(lst_points, lst_modelPoints, lst_cropCurves):
for ind, point in enumerate(points):
# rest of code
Thank you. Will have a look at that tomorrow.
Hereby the screenshot
Die orginal Python you can find in this topic.
When i use the original code i get this error

I hate doing it, but was fiddling with ChatGPT a bit (also out of curiousity) 
The Elevation Markers got placed but face the wrong direction.

When i do this they all face the same direction.
Only running into this problem and i am not sure what i am missing.
It works when i use the script for a single Scope Box.
They Elevation Markers Scope Boxes get greyed out on placement.
Dunno why. I guess something in de Python code?
Success!

I really didn’t want to resort to ChatGPT, but it got me to a solution.
Also learned you really need to ask ChatGPT the right questions and i really need
to learn Python still.
Great work @bvs1982!
Been popping in every hour or so to watch your progress. Kudos for sticking with it and showing us the process!
I couldn’t stand it that i was soooo close.
I really wanted it resolved so i could get it out of my head .
