Hello,
I’m trying to recreate the process explained here by @Gabriel_Nones-Newman Few years ago on LinkedIn but I have a little trouble with the Python part off the script.
I have this error that seems obviously right : there is a for loop for an input with a single element, but it seems to be the way that the original script is done, so maybe I lost myself somewhere …
The objective of the script, that could be deploy for a firm : “convert” a 3D View to a 2D detail View to have a fast tool to add annotations (the original Add-in for Revit has been discontinuous like this : https://www.youtube.com/watch?v=oLBTsZC0Ajk
Here is the script and screenshots

If you get that error you can simply turn the input into a list by wrapping it in [ ]. If you want to do it in a nice way so you don’t accidentally wrap a list into a list then use the following code.
If isinstance(input,list):
X = input
Else:
X = [input]
This checks if input is of type list. If not, then you make it into a list.
Thank you Daniel, can you tell me where to add this lines and if I have to “customize” them replacing words in it ?
I added a List.Create Node at Input [4] for the moment so it works but I have to continue to debug the script

It’s getting worse …
For the code in my previous message, input can be any variable you want to check for being a list (for example IN[0]) and you can replace x by any variable you want to store the variable to that you’re checking (wrapped in to a list or not depending on the type of input you’re giving it)
You can then also use the code at the top of your script where you store your IN variables to something more understandable
Is it possible that the views you’re trying to add to a sheet are already on that sheet? If so, that might explain why you can’t add the view to your sheet since it’s already there (something Revit just doesn’t allow).
