    About

    In practice. What you can do with CleanUp³.

    CleanUp³ scans a SketchUp model and removes what shouldn't still be there: unused materials, duplicate faces, stray edges and other leftover geometry that accumulates during modeling. The result is a smaller, faster file without manually hunting for clutter.

    It is entirely free and requires the TT_Lib2 library as a dependency; the latest release supports SketchUp 2022 through 2026. It fits any SketchUp user, solo or in a small studio, who regularly shares or exports heavy models and wants a quick cleanup pass before doing so.

    Practical uses

    • File size cleanupRun CleanUp³ on a heavy SketchUp model before sharing it, removing unused materials and stray edges to make the file lighter.
    • Pre-export tidy-upStrip duplicate faces and unnecessary geometry from a model before exporting it to another CAD or rendering tool.

    Pros and cons. What CleanUp³ does well, and what to expect.

    Pros

    • Completely free with no account or paid tier to manage.
    • Targets a concrete, recurring problem: bloated SketchUp files full of unused geometry.

    Cons

    • Needs the separate TT_Lib2 library installed to work, an extra setup step.
    • Scope is narrow: it cleans geometry but doesn't repair solid or inspection errors.

    When it makes sense. Keep CleanUp³, or challenge it?

    Keep if

    • Keep CleanUp³ if you regularly work with heavy SketchUp models and want a free, quick way to shrink file size before sharing or exporting.

    Challenge if

    • Skip it if your main issue is solid-geometry errors (non-solid groups, inverted faces) rather than clutter, since that is Solid Inspector2's job.

    Why this verdict

    Average

    Added value

    A free extension that removes unused geometry and materials to shrink file size carries no cost against a real, recurring modeling problem.

    Simplicity

    The tool runs a cleanup pass from within SketchUp once installed with its mandatory TT_Lib2 dependency, with no complex configuration described.

    Fit for purpose

    It performs the stated cleanup (unused geometry, materials, duplicate faces, stray edges) without a described workaround needed.

    Performance

    Scope is limited to cleanup tasks rather than broader modeling or repair, which caps its ceiling against a full modeling toolset.

    Reversibility

    Neutral score: as a free utility with no stored account data, export or portability concepts don't apply and are not covered by the sources.
