As it says in the subject line, I’m looking for a way to add a DEM file to a surface using dynamo. My attempts at using the api documentation to write python code in Dynamo has been…discouraging…and I was hoping a tool already exists or someone could give me some pointers with the code. Any help w…

Hi @rpriceAZEG6 , Are you looking to create a grid surface or TIN surface from the DEM?

@zachri.jensen Any luck with this one?

Hi See this and need some changes [image] TinSurface from 3D Faces Civil3D Hi @JPhil , To get the edges and vertices from the Faces, you would do something like this: [image] However, it will be a very heavy set of operations to deconstruct the faces into vertices and…

It is recommended to add a data clip boundary first to the Surface before adding one or more DEM files.

Never tried to use it before Thanks for this recommendation

Is there a way to add a DEM file to a surface with Dynamo?
