These are added in a process at a SketchUp portal, accessible to bona fide authors and also during EW submissions. In recent versions SketchUp also checks for a ‘signature’ for the files in the subfolder - in two added files.

The folder might also include image files for toolbar buttons, html/css/js files to make special dialogs etc. The Ruby files inside that folder can be RB or encrypted RBS or RBE files: the RBE being most crack-proof but only suitable for >v2015 users. Typically the RBZ contains an RB file which loads as SketchUp starts, and a subfolder of the same name, which contains the other files needed for the RB file to load its functions and tools. The EW only deals in Extensions, but the SketchUcation PluginStore has Extensions AND several Plugins too…Īlmost all Extensions are provided prepackaged in RBZ archives, which can be installed into the User’s Plugins folder, using the Extension Manager > Install… tool This means the Extension can be set to be enabled or disabled as SketchUp starts - using the Extension Manager. Some Plugins are created by there authors as ‘Extensions’ - often these are the more complex ones. Some Plugins are quite simple, others more complex…

These create various functions and tools to enhance SketchUp.
