Hi All,

I’m using C3D 2021 and when I try to use the node TinSurfaceExtensions.CreateSolidsAtSurface it returns the error

Warning: TinSurfaceExtensions.CreateSolidsAtSurface operation failed.  
Method not found: ‘Autodesk.AutoCAD.DatabaseServices.ObjectIdCollection Autodesk.Civil.DatabaseServices.TinSurface.CreateSolidsAtSurfaceToFile(Autodesk.AutoCAD.DatabaseServices.ObjectId, System.String, UInt16, System.String ByRef)’.

Does anyone know what the problem is?  
The operation works perfectly using normal civil 3D.

Thanks, might I ask which version you are running? It seemed to work perfectly on the demo you gave on the other thread.

Also, do you think it would work if I wrote a python script to do the same as the node?

That was awhile ago, so I don’t know what version I was using at the time. I have 2020, 2021, 2022, and 2023 installed on my machine (necessary for my job) and I keep them all updated to the latest versions all the time.

Personally, I think that would be more complex and brittle than just updating your machine so the node works correctly.
