We use Revit 2008. Whenever we export 2D plans as dwg. from drawing sheets with shared co-ordinates and open it in ACAD, UCS/WCS is right in the middle of the centee of the plan. When we export the same plan from Floor plan view with shared co-ordinates, it shows right UCS/WCS in ACAD.
Is there any problem exporting plans from drawing sheets with shared co-ordinates?
Or is there any settings that we are missing during export?

your help would be very much appreciated.
