Solid Inspector SketchUp Plugin – Full Guide, Top Features, Real Uses & Download
The Solid Inspector plugin for SketchUp is an essential extension for anyone working with solids, 3D printing, or clean model geometry. It quickly identifies and repairs hidden problems in your groups or components—such as stray edges, internal faces, reversed faces, or other non-solid issues—that can stop your model from becoming a true solid object. If you value precision, clean exports, or reliable printing results, Solid Inspector is a must-have tool in your SketchUp workflow.
If you are new to SketchUp extensions, you can first read our SketchUp plugin installation guide to learn how to install and manage plugins correctly.
What This Plugin Does
Solid Inspector scans your selected groups or components and highlights geometry issues preventing them from being solid objects, meaning closed volumes. It then offers direct repair options or guides you through the fixes. This helps you avoid problems when exporting to STL, preparing files for fabrication, or using SketchUp solid tools.
You can use Solid Inspector to:
- Check for internal faces or stray geometry
- Identify reversed faces or duplicate edges
- Repair groups so they become true solids
- Prepare models for 3D printing or CNC export
- Clean up complex components before rendering or manufacturing
- Improve overall model health and reduce errors
By maintaining clean geometry, the plugin helps you save time in post-processing, avoid failed prints, and ensure your models work smoothly in downstream workflows.
Main Features of Solid Inspector
1. Smart Issue Detection
The plugin intelligently detects the most common solid errors inside SketchUp groups or components, such as holes, stray edges, or non-manifold geometry, and presents them in an organized way.
2. One-Click or Guided Repairs
You can fix many issues automatically or manually with the plugin’s guidance. This gives you both speed and control during cleanup.
3. Export-Ready Solids for 3D Printing
Models cleaned by Solid Inspector are much better prepared for STL export, fabrication, or further editing without hidden geometry problems.
4. Works With Large Components and Scenes
Whether you are cleaning a single object or checking a larger model with many components, the plugin helps keep the process efficient.
5. Beginner-Friendly Workflow
Even if you are new to solid modeling or 3D printing, the interface is clear, the warnings are understandable, and the workflow is easy to follow.
How to Use Solid Inspector
Here’s a typical workflow with the plugin:
- Select the group or component you want to inspect.
- Activate Solid Inspector from the Extensions menu.
- The plugin lists all issues found in the model.
- Use automatic repair where possible, or manually fix each highlighted issue.
- Validate the component again to make sure no errors remain.
After cleanup, your object becomes a true solid that is ready for export, printing, or further modeling.

Real-World Use Cases
In architecture, components like window frames, façade modules, or structural nodes often contain hidden issues. Solid Inspector helps architects and modelers make sure those parts are clean before exporting, printing, or sending them into other workflows.
Product designers and digital fabrication specialists also rely on Solid Inspector to make sure parts are watertight, manifold, and printable. By checking models early, they reduce time lost on failures and corrections.

FAQ
Is Solid Inspector free?
Yes, the core Solid Inspector plugin is free and widely used. The best option is to check the official extension page for the latest details.
Where can I download Solid Inspector?
You can download it from the official SketchUp Extension Warehouse.
Which projects benefit the most?
Projects involving 3D printing, CNC export, clean components for rendering, or large architectural scenes all benefit from error-free solid geometry.
Can I still edit the model after the cleanup?
Yes. Once cleaned, the group or component behaves like any normal SketchUp solid. You can edit, scale, or integrate it into other assemblies easily.
