Let’s reply here instead of the other thread you continued as likely the issues aren’t the same.
In your case everything’s is working until the last node - Can you tell us:
- what package is that from.
- which version of that package.
- which Revit year and build.
- and which Dynamo version.
I would add to what @JacobSmall has said and say could you post what is outputted from that last node.
This is because if it uses python it might be displaying a error but in a different way to the usual yellow messages(display traceback errors as output if issue).
This script i made to convert DWG link LINE TO Pipe.
Package - MEPover
Package Version - 2019.12.01
Output till 2nd last nodes is perfect as required. but last node output is null.
