There is a detailed review of Tgi3D SU Amorph by the CatchUp editor Rich O'Brien on pages 14 to 18. Rich O'Brien suggests:
"[Tgi3D SU Amorph] really is bringing a level of modeling accuracy to SketchUp that hasn't been so readily possible before. It's not like other plugins that offer great fixes or quicker methods. It's introduced a whole new method of modeling, a cunning set of tools and features that haven't been explored before."
