Script not working on multi floor project

Revit
,
1

I am trying to get this script to work better for setting the gridlines to the crop region of a view. currently this will work pretty flawlessly when you are on the first floor of a building. Once you go to the second, third and so on it is just giving errors within the python script. I do not know enough about python to figure out what is happening here.

Is there anyone that would be able to take a look at this script and the Python script to see what could be causing this? Within the python line 62-63 - viewRange = activView.GetViewRange()
cutOffset = viewRange.GetOffset(PlanViewPlane.CutPlane)
i am wondering if this might have something to do with it.

thank you in advance for any and all help

Are force rerunning the graph each time? Ether by using force rerun, closing and opening it, or changing your t/f on the active view node?

Also, what is the error?

So for this given project i have a ton of segment views and i will run this for each of the segment views. when i am working on the first floor views it seems to work fine but not on the others.

Normally i would just use the Dynamo player and i will hit the play button for each view.

i leave everything open, and for the boolean i normally leave that on false.

Try closing the graph after each run and let me know. Where did you get the python script?

At a quick glance, I cannot find where it is operating on any of your inputs.

this is all from something that i found on the internet. even closing it and then reopening dynamo it doesnt seem to make a difference. i know that it is never good to do that but within a post i saw that this worked for them so i opened up dynamo and started to build it off the images that were uploaded.
