On-Demand Plugin/Extension Loader
This tool lets you use plugins/extensions without installing them (good for computer labs or keeping SketchUp lean).
On-Demand Plugin/Extension Loader

This SketchUp extension was created out of a need for having extensions available in a “locked down” computer lab setting (similar to my solution for AutoCAD). It also provides an easy way to use extensions in SketchUp without having to install them - therefore making SketchUp start (and possibly run) faster.

To use this tool, you need to save extensions (their RB files and any folders that the plugin author packages with them) to a convenient location (a folder on your harddisk or network drive or a USB stick). Make sure, the file/folder structure remains intact (exactly as it would be inside SketchUp's own Plugins folder).

With the menu items that this tool provides, you can then:

  • On-demand load a single plugin/extension (RB file). After loading the plugin, it will be immediately available for use.
  • On-demand load several plugins/extensions at once that are all contained in a folder. For this option, simply select any file within the folder and all RB plugins will be loaded.
  • Permanently install an RBZ or ZIP plugin/extension in SketchUp. This is simply another way to do what the "Install Extensions..." button does.
  • Manage Extensions. This is simply a convenient shortcut to the preferences panel. You can disable/enable plugins here.
  • If you get stuck, the About option has some information and allows you to contact the author.

Some Ideas:

  • Organize your extensions by task (e.g. woodworking, modeling, etc.) into folders and load each group only when needed.
  • Create a "Plugins" folder in your Dropbox and have it sync across all your computers. Then load extensions as needed using this tool.
  • In a computer lab, permanently install this extension and distribute extension collection folders to students on USB sticks. Let them load whichever extensions they need.

Please note: After restarting SketchUp, the loaded extensions become unavailable and you will have to load them again when you need them (this is by design). To install extensions permanently, use the install function.
