How to display Civil3D's Tinsurface in Dynamo

I am looking for a way to display Civil3D Tinsurface in Dynamo.
I tried the method you previously answered, but it did not work well for this Surface.

How can I make a surface created in Civil3D available as a Dynamo Geometry?
Please check the related files attached.


surface.dyn (10.3 KB)

I’m using Civil 3D 2024 too and can get the triangles:

Try getting the surface using the selection nodes from the Civil 3D Toolkit as I did or by using the selection nodes on the Civil 3D category instead of “select object”.

Thank you for your response!
I am now able to display the Surface using the method you described.
However, sometimes I get an image error, although I attached the first one.

You’re getting a warning related to the geometry scaling, as arule of thumb don’t change the scaling and ignore the warning.

I explained a bit this in the community conversations (go to minute around 28): https://www.youtube.com/watch?v=MIjqh0LZ45E&t=2007s
