@Jack2022 Really appreciate the time taken to write this out. Although I am a bit confused on something.
When you use the circle method to type in the coordinates for the internal origin, why not just change the coordinates in the georeferencing dialog box to match the Revit ones? The reason I'm asking is because I tried to coordinate a model with Revit using the dialog box and it didn't work before, I just don't understand why?
I can't wait for this to click but I've been going over all available info for months and still twisted up!
