Topo from Excel Problem

Hello, I am having a problem with my script I made that creates a topo from Excel in Revit. When I run the script it gives me an error (image below) and I cannot figure out why it is doing it.

I don’t think I’m far off but I cannot figure out what I’m missing.

Can anybody help ?

Thank you

Hi @Kieran_Atherton

Currently your connecting points to topography node. You need to use Topography.ByPoints node.

Thank you kulkul, It was driving me mad

I used your script for my project, thanks for sharing,
I dont know why it seems to not generate all points… and create random topo…

If I compare to the cad, it makes no sense
