There are two ways to specify area in a catchment.

The first involves directly entering the area in the Property Editor or FlexTable for the catchment.

The second is based on the scaled area from the drawing. This can only be used if the drawing is scaled and the units have been correctly identified. Bentley StormCAD displays the scaled area in the Property Editor for the catchment and you must copy that value in the Area attribute. For more information, see Catchment-Geometry.

It is possible to have an area that is not uniform in terms of runoff. For more information, see "Defining CN Area Collections for Catchments" .
