How to remove results that have a small area

Version 1

    Determine whether a result with an area of only a few square db units is worth keeping.
    If not then remove small shapes from the output layer by adding an AREA filter after the boolean.

    Example:
         Assume that the output from the following AND occasional produces unwanted results that are less than 2 sq. db.

     

         PADO = AND PAD2 METAL4


         PADO_SMOOTHED = AREA PADO > .000002 // eliminate small errors, under a couple square nm.
