Solid Inspector² is a critical SketchUp extension used to identify and repair "non-solid" geometry, ensuring models are watertight for 3D printing and Boolean operations. Developed by Thomas Thomassen (thomthom), it is the industry standard for cleaning up complex components. 1. Download & Installation Guide
Solid Inspector² is available for free through several official channels:
SketchUp Extension Warehouse: The most direct method. You can search for "Solid Inspector 2" within SketchUp's internal Extension Warehouse window and click Install.
SketchUcation PluginStore: An alternative popular community repository for downloading the RBZ file.
GitHub Repository: For advanced users wanting the open-source files directly from the developer. Requirements:
Version: SketchUp 2014 or newer (Older versions require the original Solid Inspector v1). solid inspector 2 sketchup download
Dependencies: Often requires the TT_Lib² library to function correctly. 2. Key Features & Functionality
The extension analyzes groups and components to ensure they are "manifold" (closed volumes with no internal or stray geometry).
Title: Why Every SketchUp Woodworker & 3D Printer Needs Solid Inspector² (And Where to Download It)
Post Date: 2024/2025 Update
If you’ve ever spent 20 minutes trying to figure out why SketchUp won’t let you click "Subtract" in the Solid Tools, you’ve met the invisible enemy: non-solid geometry. Solid Inspector² is a critical SketchUp extension used
For woodworkers, 3D printers, and CNC users, a "solid" isn't just a shape—it's a mathematical necessity. Enter Solid Inspector² by TIG.
Solid Inspector 2 is a SketchUp extension that diagnoses and helps repair geometry problems preventing a model from being a valid “solid” (a closed, manifold, watertight volume). It’s widely used by architects, makers, 3D-printing enthusiasts, and anyone exporting SketchUp models to formats or workflows that require solid geometry (STL exports, Boolean operations, physics simulations, and some CAD imports).
Solid Inspector² is a free (donation-ware) extension that scans your model, highlights the exact edges or faces breaking the solid, and often gives you a one-click "Fix" button.
It fixes three main problems:
Yes. ThomThom has historically provided this tool as a free resource for the community. However, if you find yourself using it daily (especially if you are a 3D printing enthusiast), the developer often accepts donations or has a "Pro" version of other tools that helps support their work. Title: Why Every SketchUp Woodworker & 3D Printer
If you are a SketchUp user working with 3D printing, woodworking, or complex architectural geometry, you have likely encountered the dreaded "Group is not solid" error. This is where Solid Inspector² (the updated version of the classic Solid Inspector) becomes an essential tool.
Let’s walk through a practical repair scenario.
Step 1: Select your object Click to select the group or component you suspect should be a solid.
Step 2: Run the Inspector
Go to Extensions > Solid Inspector 2 > Inspect (or click the magic wand icon on the toolbar).
Step 3: Analyze the results A dialog box appears. The interface is color-coded:
Step 4: The "Fix" Button Here is the magic: If you have a simple missing face, click the "Fix" button. Solid Inspector 2 will automatically attempt to cap holes. For complex issues, click on a highlighted red edge. The tool will zoom to the problem area.
Step 5: Manual vs. Automatic
