Create an Area Plan in Autocad Civil 3D

1. Click Architecture tabRoom & Area panelArea drop-down  (Area Plan).
2. In the New Area Plan dialog, for Type, select an area scheme.
3. 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.
4. 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.
5. For Scale, select the area plan scale.
6. Click OK.
   Revit prompts you to automatically create area boundary lines associated with all external walls. 
7. 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
8. Add more area boundaries, as needed.
