Does anyone know any alternative package for this Genius Loci node? or a working code in revit 2025?

You can use OOTB to get the location and there is still the Genius Loci Element Reference node in R2025

Hi @rajeshjamariya16 try set the node to cpython 3, guess it will work then

Managed to create an alternative code in the process!
