Extaction points from a topographic surface from Rhino on dynamo

Hi There!:wink:
I created a topographic surface on Révit due to rhynamo, because, indeed, my topographic surface comes from Rhino. :yum:
It works but not totaly!
Indeed Révit upload this shape like a conceptuel mass with a category.
Unfortunatly I can’t do anything with that.:sweat_smile:
Even, when I cut into it I can’t see the thikness of this shape.
So, don’t you think, I have to extract points from this surface and create a list points folder that I can use to design the topographie in Revit? !
If you Have tips feel free to give me those!!:relaxed:
Thank you very much!
