This might just be a miscommunication, but I want to drive the point home.
The internal origin is hard coded; everything else moves around it; it does not move, it does not get transformed or translated; it is static; never changing. It is one of the few aspects of a Revit model which is exposed to users and that concrete…
So to ‘move the internal origin’, you actually have to move every model element from the current position to a new position, including views, annotations, sketch planes, crop regions, model elements… the list goes on and on. That likely sounds like a bad idea, because it is.
Instead utilize the survey point and project base point to report the data as you need it to. To relocate the survey point/project base point you can review the solution here: Move survey point - #11 by Alban_de_Chasteigner
