Sketchup Make 2017 ^new^ -
The official policy from Trimble is that existing users may continue to use Make 2017, but they no longer distribute it. However, many tech archives and third-party sites still host the installer.
The modern SketchUp Free runs in a browser. If your internet dips or you want to model on a laptop in a workshop, you’re out of luck. Make 2017 runs entirely locally. sketchup make 2017
