Transform coordinates - XY points

I am trying to get element’s XY position points in the Survey Point coordinate system.
I am getting XY position points in the Project Base Point coordinate system, but how do I transform them to Survey Point?
I attach example dynamo and revit files.

Hi @Julian_Krab,

With a python node and the help of the API, it’s quite easy :

P.S : The python script will only work in Revit 2018 and Revit 2019 because of a change to the API.
Use the code in the link above for previous versions.


You are amazing @Alban_de_Chasteigner :slight_smile:

Have you tried the OOTB Geometry.Transform?

@Vikram_Subbaiah now I did tried it, and it gives wrong results :slight_smile:

@Julian_Krab How about this?

@Vikram_Subbaiah this one works! Thank you too!
