    About

    In practice. What you can do with Solid Inspector².

    Solid Inspector2 checks SketchUp groups and components for the errors that break solid modeling: non-solid geometry, stray or useless faces, inverted faces and hidden edges. It then offers automatic repair actions instead of leaving the fix to manual trial and error.

    The extension is entirely free and open-source, requiring SketchUp 2014 or later. It fits a SketchUp user preparing a model for 3D printing or for export to a format that demands clean solid geometry, and pairs naturally with CleanUp3 for broader file tidying.

    Practical uses

    • 3D-print prepRun Solid Inspector2 before sending a model to a 3D printer to catch non-solid groups and inverted faces that would break the print.
    • Export validationCheck a component for stray or hidden-edge errors before exporting it to another CAD format that requires solid geometry.

    Pros and cons. What Solid Inspector² does well, and what to expect.

    Pros

    • Free and open-source, with no account or paid tier to manage.
    • Automatic repair actions save manually hunting for the broken face or edge.

    Cons

    • Limited to solid-geometry inspection and repair, not a general modeling or rendering tool.
    • Requires SketchUp itself (2014 or later) to run, so it adds no value without that license.

    When it makes sense. Keep Solid Inspector², or challenge it?

    Keep if

    • Keep Solid Inspector2 if you regularly prepare SketchUp models for 3D printing or for export formats that require solid geometry.

    Challenge if

    • Skip it if your models never need to be solid (pure visualization or 2D work), since the tool solves a problem you don't have.

    Our verdict. What to know about Solid Inspector².

    Why this verdict

    Average

    Added value

    A free, open-source extension that catches solid-geometry errors before export or printing avoids costly rework at no cost itself.

    Simplicity

    It runs an inspection pass inside SketchUp with automatic repair actions, with no complex setup described beyond installing the extension.

    Fit for purpose

    It detects and repairs the stated solid-geometry issues (non-solid groups, inverted faces, stray or hidden edges) without a described workaround.

    Performance

    Scope is deliberately narrow to solid-geometry inspection and repair, which caps its ceiling against a general modeling toolset.

    Reversibility

    Neutral score: as a free, local plugin with no account data, export or portability concepts don't really apply and aren't covered by the sources.
