Changing Active Project Location / Project Base Point

Thanks for the response.
I should have added more info as context. This is in reference to my previous thread.
I am trying to use @Konrad_K_Sobon’s Elements in Space node which calls the Revit API IsPointInSpace method from the Space class. I may be misunderstanding but I didn’t think that would help. If I got the correct location, how would I use it to affect the space location from a linked instance? I can’t change the type to a different class or create a new element or else I lose the ability to use that method.
