If you want to Export from Revit to AutoCAD with coordinates, you will need to do the following: -
Make sure you ‘Export the view’ on its own, not on a drawing sheet.
Go to "R" button (Top left-hand corner), then select Export - Scroll to bottom and open Options - Export Setups DWG/DWF.
Go to Units & Coordinates tab. Set correct DWG unit to match Revit unit. Set Coordinate System Basis to Shared.
Open view (not sheet). Set view to True North.
Now before you export, make sure your Revit model coordinates match the survey coordinates for your actual north and your true north is set correctly.
Good luck
