I missed something really obvious @Petar_Penchev1. I feel like a real idiot.
I certainly appreciate the help though. I forgot the “Get Current Document” in front of “Get Active View” node.
This code seems to not need any python or packages. At least from what I can remember.
Which hopefully means it won’t break on using in future revit releases.
Here’s the code (Sorry for the mess). Don’t have time to clean up.
