Project Base Point affecting Windows Opening

Hi All, I had two models which have different Project Base Point. In my script, I tell dynamo to obtain coordinates of the link archi and attach an opening to my structural model.

I DO NOT wish to change the base points in the models, just sufficient for the script to place it at the right position.

Script below is just extracting the base points of both file, can anyone guide me on how to ensure archi file base point align to structural?
