CleanUp³ is a robust SketchUp extension designed to optimise 3D models by purging unused data and repairing complex geometry. This utility functions as a comprehensive maintenance toolkit for SketchUp, specifically engineered to streamline heavy project files. It automates the removal of redundant elements such as unused materials, styles, layers, and components that often bloat file sizes. Beyond simple purging, the tool identifies and resolves common modelling inefficiencies, including stray edges, zero-length segments, and fragmented geometry. By merging coplanar faces and unifying normals, it ensures that the underlying mesh remains clean and computationally efficient, which is essential for maintaining smooth viewport navigation and reducing render times in large-scale architectural visualisations.

The download is a 61 KB file containing .ZIP files.

Users integrate this plugin directly into the SketchUp Ruby environment, where it appears as a dedicated dialogue box. Professionals typically run the cleanup process before finalising a model for export or rendering to ensure optimal performance. The interface provides granular control over which parameters are purged or repaired, allowing for targeted optimisation of specific model components. It is best practice to perform a backup of the file before running intensive cleanup operations to maintain version history.

CleanUp³ is indispensable for architects and interior designers working on complex residential, hospitality, or commercial projects where model weight can hinder productivity. It is particularly valuable during the mid-to-late stages of design development when file bloat from repeated imports and iterative changes becomes apparent. By maintaining a lean and efficient digital environment, this tool supports seamless collaboration between project team members, ensuring that shared models remain manageable and free from redundant data that might otherwise lead to software instability or performance degradation.
