- Click Architecture tab Room & Area panel Room & Area panel Area drop-down Area drop-down   (Area Plan). (Area Plan).
-  In the New Area Plan dialog, for Type, select an area scheme. 
- Select a level for the area plan view. If you select more than one level, Revit creates a separate area plan for each level and groups them by area scheme in the Project Browser.  
- To create unique area plan views, select Do not duplicate existing views. To create copies of existing area plan views, clear Do not duplicate existing views.  
- For Scale, select the area plan scale. 
- Click OK. Revit prompts you to automatically create area boundary lines associated with all external walls. See Area Boundaries.  
- Select one of the following: - Yes: Revit places the boundary lines along the exterior walls of a closed loop. 
- No: You sketch the area boundary lines. 
 Tip: Revit cannot automatically create area boundary lines in external walls that are not closed in a loop.  Tip: If the project includes a ruled curtain system within the exterior wall loop, you must sketch the area boundary, because ruled curtain systems are not walls.  
- Add more area boundaries, as needed. See Create Area Boundaries.
