Solid Inspector SketchUp Plugin – Free Download, Features & Complete Guide
The Solid Inspector SketchUp plugin, officially known as Solid Inspector², is a free extension for finding and fixing geometry problems that prevent groups or components from becoming valid solids. It detects holes, stray edges, internal faces, reversed faces, and other non-manifold geometry that can cause problems with SketchUp Solid Tools, STL export, CNC work, and 3D printing.
If you are new to extensions, read our SketchUp plugin installation guide. You can also explore our free SketchUp plugins collection and use CleanUp³ before running Solid Inspector² on complex models.
What Does Solid Inspector² Do?
Solid Inspector² scans the selected SketchUp group or component and highlights the exact areas that stop it from forming a closed volume. Instead of searching manually through complex geometry, you can move directly to each issue and repair the model efficiently.
- Find holes, gaps, stray edges, and internal faces
- Identify reversed faces and non-manifold geometry
- Prepare watertight models for 3D printing and STL export
- Improve compatibility with SketchUp Solid Tools and Boolean operations
- Check imported components before rendering or fabrication
For best results, save a backup of the model, clean unnecessary geometry, run Solid Inspector², repair the highlighted issues, and validate the object again until SketchUp recognizes it as a solid.

How to Install SketchUp Plugins
What Is the Solid Inspector² SketchUp Plugin?
Solid Inspector² is a free SketchUp extension developed by ThomThom. It is designed to help users inspect SketchUp geometry and detect problems that stop a model from being recognized as a solid. This is especially important when preparing models for 3D printing, Boolean operations, solid tools, or clean architectural modeling.
In SketchUp, a solid object must be a closed volume with no holes, loose edges, internal faces, or broken geometry. The Solid Inspector² SketchUp Plugin highlights these issues so you can quickly understand what needs to be fixed. 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 Solid Inspector².
Why Use Solid Inspector²?
The Solid Inspector² SketchUp Plugin is one of the most valuable tools for SketchUp users who work with solid modeling, 3D printing, fabrication, and advanced modeling workflows. Many SketchUp models appear correct visually, but hidden geometry issues can prevent them from being recognized as valid solids.
The Solid Inspector² SketchUp Plugin automatically detects geometry problems and guides users directly to the areas that need attention. Instead of searching manually through a complex model, you can quickly locate and fix errors that affect solid operations and model integrity. For even better model optimization, many users combine Solid Inspector² with the CleanUp³ SketchUp Plugin before performing solid validation.

When Should You Use It?
The best time to run the Solid Inspector² SketchUp Plugin is before using Solid Tools, exporting files for 3D printing, sharing production models, or completing detailed modeling projects. Regular inspections help prevent geometry errors from becoming larger problems later in the workflow.
- Before using SketchUp Solid Tools.
- Before exporting models for 3D printing.
- After creating complex geometry.
- After importing third-party models.
- Before manufacturing or fabrication workflows.
- Whenever a SketchUp model fails solid validation.
How to Use the Solid Inspector² SketchUp Plugin
After installing the Solid Inspector² SketchUp Plugin, you can launch it from the Extensions menu in SketchUp. The plugin automatically analyzes your selected group or component and identifies geometry problems that prevent it from becoming a valid solid object.
- Open your SketchUp project.
- Select the group or component you want to inspect.
- Launch Solid Inspector² from the Extensions menu.
- Review the detected geometry issues.
- Navigate to each highlighted problem area.
- Fix holes, stray edges, or internal faces.
- Recheck the model until it becomes a valid solid.
Important Tip Before Running the Plugin
Although the Solid Inspector² SketchUp Plugin helps locate geometry issues, it does not automatically solve every modeling problem. Understanding basic SketchUp geometry principles will help you fix detected issues more efficiently.
For best results, save a backup copy of your SketchUp file before making major geometry changes. This allows you to compare versions and restore the original model if needed.

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.
