Transform coordinates - XY points

[Julian_Krab]

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 :

Transform point v1.dyn (9.2 KB)

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.

Have you tried the OOTB Geometry.Transform?
