Double Cut for SketchUp - Permanent License 

Make SketchUp cutting components (windows, doors) automatically cut through thick walls!  Not only that, if you move the component after inserting it, the double-cut will automatically be updated, saving you valuable time.

A must-have plugin for architects and interior designers, Double-Cut works behind the scenes to adjust window and door openings created by SketchUp cutting components as you edit them.

Double-Cut reacts automatically to the standard SketchUp tools.  Move a door and the opening automatically moves with it.  Scale a dynamic window component and the opening resizes.
