@lastmonth There are a couple of things wrong in the graph. First, it will not work the Surface created using Geometry in Dynamo, and it has to be a Surface or Face selected from Revit, another thing is Location Line should have input as String which you can use it from **Wall Location** node. I have attached sample Dynamo file, give it a try and let me know if you have further question. (Please create one Surface in your Revit project file and select it using the Select it using **Select Face** node in my graph.)

thank you very much.

I understand . and I have test your file. It’ok.

but if I want to use surface created from dynamo… not a Surface or Face selected from Revit.

No, you cannot use the Geometry created in Dynamo, it has to come from Revit only.
