SketchUp 6 is considered obsolete (end-of-life). It cannot read newer .skp files from versions 2013 onward. It runs on Windows XP/Vista and Mac OS X Tiger/Leopard (PowerPC & early Intel). Use only for legacy file support or vintage modeling practice.
Let’s not get lost in nostalgia. As much as I love Version 6, it is objectively inferior for professional work today.
The biggest contribution of SketchUp Version 6 was the workflow. Before Version 6, 3D modelers thought in vertices, edges, and polygons. After Version 6, a generation of designers thought in surfaces .
Remember when SketchUp was owned by Google? 🕰️
