CleanUp³ SketchUp Plugin – Free Download & Complete Guide
CleanUp³—also searched as CleanUp3, CleanUp SketchUp, or the Clean Up SketchUp plugin—is a model-optimization extension by ThomThom. It removes unnecessary geometry and unused model data so large SketchUp files are easier to navigate, edit, and prepare for rendering.
What Is CleanUp³ for SketchUp?
CleanUp³ is designed to clean and optimize SketchUp models by addressing duplicate faces, stray edges, unused materials, hidden geometry, and other data that can make a project unnecessarily heavy. It is particularly useful after importing CAD drawings, downloading 3D Warehouse assets, or combining many components in an architectural scene.
A cleanup can reduce clutter and may improve file size and responsiveness, but results depend on the model and the options selected. Always save a backup before processing an important project. For more useful extensions, browse our free SketchUp plugin collection.
Why Use the CleanUp SketchUp Plugin?
Complex models gradually collect unused components, duplicate geometry, materials, styles, scenes, and tags. CleanUp3 brings the most common optimization tasks into one controlled process, helping architects, interior designers, students, and visualization artists maintain a cleaner working file.
Cleaner, more manageable models
Removing stray edges and unnecessary geometry makes a model easier to inspect and edit. This is especially helpful with imported CAD files and third-party furniture models.
Better performance in large projects
Purging unused data can reduce file weight and improve navigation. A lighter model is also easier to organize before exporting to another application or starting a rendering workflow.
Main cleanup features
- Remove duplicate faces and stray edges.
- Merge identical materials and reduce material clutter.
- Purge unused components, materials, tags, styles, and scenes.
- Clean selected geometry or the entire model.
- Optimize downloaded 3D Warehouse assets before use.
- Generate a cleanup report so you can review the result.
How to Install and Use CleanUp³
- Download the extension from the official SketchUp Extension Warehouse.
- In SketchUp, open Extensions → Extension Manager.
- Choose Install Extension and select the downloaded RBZ file.
- Open the model you want to optimize and save a backup copy.
- Go to Extensions → CleanUp³, choose the required options, and run the cleanup.
- Review the report and inspect the model before saving.
If this is your first RBZ installation, follow our step-by-step SketchUp plugin installation guide.
When Is CleanUp3 Most Useful?
The plugin is most valuable when a SketchUp file has become slow, contains many imported assets, or needs preparation for rendering and export. It can also help before sharing a model with a team because a cleaner file is easier to understand and maintain.
Cleanup is not a substitute for good modeling habits. Use groups and components consistently, assign tags correctly, keep raw geometry on Untagged, and avoid importing more detail than the project requires.
