A SketchUp Ruby Extension that provides some tools to make developers’ lives easier, including a better, badder Ruby console and a unit test runner we affectionately call “TestUp.” More tools to come.
The latest and greatest (definitely still in beta) is available as an RBZ. Download the file. Then inside SketchUp, select Preferences > Extensions > Install Extension and select the RBZ file you just downloaded. Voila! SketchUp installs the extension. You’ll find a new menu under Tools > Developer with all the goodies.
