This tool lets you use Ruby scripts & extensions without installing them (good for computer labs or keeping SketchUp lean).
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. In addition, you can use this tool to run any external ruby code (e.g. for development purposes).
After installation, this is how this extension appears under the “Extensions” menu:
To use this tool, you need to save extensions (their Ruby – RB – files and any folders that the extension 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 Ruby file / extension (.RB). After loading the file / extension, it will be immediately available for use (and remains so until SketchUp is restarted).
- On-demand load several Ruby files / extensions (.RB) at once that are all contained in a directory. Those will then be immediately available for use (and remain so until SketchUp is restarted).
- Select a directory (e.g. on a USB-drive) that contains Ruby files or extensions that are then automatically loaded each time SketchUp starts. This is in addition to the regular SketchUp Plugin directory, which contains all installed extensions.
- Permanently install an .RBZ or .ZIP extension in SketchUp. This is simply another way to do what the “Install Extensions…” button does but in this case also allows installing from .ZIP files.
- Manage extensions. This is simply a convenient shortcut to the Extension Manger Window. You can install / disable / enable extensions here.
- If you get stuck, the About option shows a website with information, discussions, and a way to contact the author.
Some ideas for working with this tool:
- Organize your extensions by task (e.g. woodworking, modeling, etc.) into folders and load each group only when needed.
- Create an “Extensions” folder in your Dropbox / OneDrive and have it sync across all your computers. Then load extensions as needed from there 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.
Use the submenu items under Extensions/Plugins > Ruby / Extension Loader

If you cannot install this extension, then you can save its unzipped files anywhere (e.g. your USB memory stick – the H: drive in my case) and then load it into SketchUp (no restart required!) by opening the Ruby Console (Window > Ruby Console) and entering this (modify for your setup):
- While this loading approach will work in most cases, it may fail to load some (especially larger) extensions due to programmed-in dependencies.
