CleanUp³ SketchUp Plugin – Free Download, Features & Complete Guide
CleanUp³ is one of the most useful free SketchUp plugins for cleaning, optimizing, and improving heavy SketchUp models. It helps remove unused geometry, fix unnecessary edges, purge unused materials, and make your SketchUp workflow faster, lighter, and smoother.
What Is the CleanUp³ Plugin?
CleanUp³ is a free productivity extension for SketchUp developed by ThomThom. It is designed to clean up and optimize SketchUp models by removing unnecessary geometry, unused materials, duplicate faces, stray edges, and other model elements that can slow down your project.
If you work with downloaded 3D models, imported CAD files, furniture models, interior scenes, landscape files, or large architectural projects, CleanUp³ can help keep your SketchUp file lighter, cleaner, and easier to manage. You can also explore our free SketchUp plugin collection to build a stronger modeling workflow.
If you are new to SketchUp extensions, you can first read our SketchUp plugin installation guide before installing CleanUp³.
Why Use the CleanUp³ SketchUp Plugin?
The CleanUp³ SketchUp Plugin is one of the most useful productivity extensions for SketchUp users who work with complex architectural, interior design, landscape, and 3D visualization projects. Over time, SketchUp models can become filled with unnecessary geometry, duplicate faces, unused materials, hidden edges, and imported objects that reduce performance and increase file size.
The CleanUp³ SketchUp Plugin helps remove these problems automatically, allowing designers to maintain cleaner models, faster navigation, and a more efficient workflow throughout the entire design process.
Cleaner SketchUp Models
The CleanUp³ SketchUp Plugin removes unnecessary geometry and helps keep SketchUp projects organized and easier to edit.
Better Performance
By reducing extra geometry and unused data, the CleanUp³ SketchUp Plugin can improve SketchUp performance, especially in large architectural projects.
Useful Before Rendering
Cleaning a SketchUp model before rendering can reduce file weight and improve workflow efficiency in rendering software. If you want to improve your rendering workflow, you can also explore our Lumion rendering training .
Great for Imported Files
The CleanUp³ SketchUp Plugin is especially useful for imported CAD files, downloaded furniture models, and 3D Warehouse assets.

How to Use the CleanUp³ SketchUp Plugin
After installing the CleanUp³ SketchUp Plugin, you can access it from the Extensions menu inside SketchUp. Before running the plugin, it is recommended to save a backup copy of your project, especially when working on important architectural or interior design files.
- Open your SketchUp model.
- Create a backup copy of the project.
- Go to Extensions → CleanUp³.
- Select the cleanup options you want to apply.
- Run the cleanup process.

- Save the cleaned SketchUp file.
Important Tip Before Using the CleanUp³ SketchUp Plugin
The CleanUp³ SketchUp Plugin can remove unnecessary geometry, unused materials, duplicate faces, and stray edges from your SketchUp model. Although this improves performance and organization, every project is different.
For this reason, it is always recommended to keep a backup version of your original SketchUp file before running the plugin. This allows you to compare results and restore the original model if necessary.
