 - in NCC Tool, the new Geometry object that is created on copper clear now has the solid_geometry attribute where the geometry is stored not only in the obj.tools attribute
+- Copper Thieving Tool - added units label for the pattern plated area
+- Properties Tool - added a new parameter, the copper area which show the area of the copper features for the Gerber objects
