Syntax

   @Area([REJECTABLE,][[(SLOPED_AREAS|VOLUME),]<multiplier>]) 
   
Arguments

   REJECTABLE

      Rejects features if this keyword is specified.

      Range: N/A

   <multiplier>   
      By default, the area returned is in coordinate units squared. The 
      multiplier, if specified, can be used to convert to other units. The 
      default is 1.
      
      Range: Real Number

   SLOPED_AREAS
      This calculates the area of the planar polygon or face with respect to the plane.

   VOLUME
      This calculates the volume of the solid (not the area)
      
Description

   The @Area function calculates the area of a polygonal feature. The function 
   correctly handles both polygonal features and polygonal features with holes. 
   For point and linear features, 0 is returned. The optional multiplier can be 
   used to convert the return value from ground units squared to units more 
   useful to the caller.
