To copy a room design that you wish to use in another job first;
• Save the job.
• Go to the Reports -> Utilities -> Export Order and name the room as you choose.
• Open the Job you want to have the saved room in and start a new room in plan view.
• Then from the Reports -> Utilities -> Import Order, select the room you previously exported;
You can now go back to the Plan, Elevation views and you will see your room has now been imported.
The room will keep its original Job Properties settings, so you will have to change the Doors, Materials, and Construction Method if desired.
