Revit2025 Make load Lane Script by Dynamo, But error (Revit change Topography → Toposolid)

Revit ver : 2025.2
Dynamo ver : 3.2.1

hello. I previously used Revit 2019.2 and upgraded to Revit 2025.2.
A problem occurred while using the dynamo script, which worked well when using the previous version.
The basis of terrain modeling was “topography” in the previous version, but the current version uses “toposolid”.
It was changed to use it as a base, and as a result, the script part of the attached photo did not work.
It is done.

How can I change this part to make it work as before?

@jvyoo8340 What happens if you use this:

Toposolids won’t work off the Topography.Mesh so you will need to revisit this workflow. Fortunately we have a lot more options now.

What were you doing after pulling the surfaces from the mesh?

Thanks. Num2 is solved ! PoluCurve.
ByJoinedCurves was solved by simply upgrading the version and using the same node.

How did you solve it? Just declaring it solved doesn’t help the rest of the community very much.

I’m attaching a photo because I think it’s easier to see it than to say it in words.
Num2(ByJoinedCurves) is solved. but Num1 isn’t solve.
I tried to solve this problem by using a Python node between Select Model Element and Topography.Mesh, but the process of creating a list of coordinate points failed.

Why do you need the direct shape?
