Add Polygons, then calculate copper Area. Enlarge Polygons, and then calculate copper again. Output to Fab3000 command window.
-- This tutorial demonstrates Add Layer, Point Array & Polygon creation,
-- Copper Area Calculation, Selection Sets, and more.
--Set user units to inch.
fab3000.dbSetUserUnits( fab3000.dbcInch )
--Create Layer
fab3000.uiEditAddLayer( "metal", 1 )
--Create Outer Polygon

--Create Inner Polygon (notice its a clear composite)
