I thought someone might have a different idea from mine.
By providing the script I used, I don’t want the message to be “my script doesn’t work”, because in reality it doesn’t give any errors, it just doesn’t do what I want it to do…
I took the script from this page “ Revit CivilConnection 2025 - Open Civil Document, Get Surface Workflow - #7 by dave.middle4ZNRV “, but actually mine is not a topographic surface (the surface is the triangular one you see above).
I also tried using the BriMohareb_2025 package, but I get an initial error (I am attaching that as well).
