MeshInspector: How to Use the Measure Thickness Tool
The Measure Thickness Tool in MeshInspector is an essential feature for analyzing 3D models before printing. It helps identify areas that might be too thin to print correctly, preventing failed prints due to weak sections. In this article, we’ll walk through how to use this tool effectively, including the newly introduced Sphere method for more precise measurements.
Why Measure Thickness Matters
Most 3D printers have a minimum resolution limit. If your model has areas that are thinner than this limit, it may result in weak points or printing failures. The Measure Thickness tool creates a color-coded map of your model, allowing you to quickly spot thin regions that might cause issues.
Setting Up Your Model for Accurate Thickness Analysis
To get the most accurate results, it’s crucial to inspect the geometry of your mesh. The tool measures thickness by calculating the distance from one vertex to the opposite surface. The more vertices your model has, the more accurate the measurement will be.
1. Visualize Mesh Edges: Press the L button to display the edges of your model.
2. Check Geometry: If your model has a minimal number of faces or vertices (common in CAD-exported STL files), consider remeshing or subdividing the model. This ensures the Measure Thickness tool can work with higher precision.
Using the Rays Method
The Rays Method is straightforward and works well for models with relatively simple geometry. It measures thickness by shooting rays from the surface and calculating the distance between opposite sides.
How to Use the Rays Method:
1. Activate the Measure Thickness tool.
2. Set the thickness required for your 3D printer in the "Enough Thickness" parameter.
3. The color map of the progress bar will change dynamically as you adjust the thickness settings:
- Green areas indicate sufficient thickness.
- Red or yellow areas signal thin sections that may cause issues.
The progress bar helps you easily interpret these colors and identify problem areas in your model.
Using the Sphere Method
The newly introduced Sphere Method provides a more precise way to measure thickness for complex geometries and internal structures. This method calculates thickness by finding the largest sphere that can fit between two surfaces, offering better accuracy for internal measurements.
How to Use the Sphere Method:
1. Switch to the Sphere Method.
2. Apply this method to see a detailed thickness map, particularly useful for models that require high internal precision, such as medical devices or industrial components.
Additional Features of the Measure Thickness Tool
MeshInspector also offers additional features for more detailed analysis:
- Click on any surface to get specific thickness measurements in that area.
- Use quick buttons to identify the thickest and thinnest parts of your model instantly. This helps you locate critical areas that may need adjustment.
Fixing Problem Areas
Once you’ve identified the problematic zones using the Measure Thickness tool, you can fix these areas using other tools in MeshInspector, ensuring that your model is ready for 3D printing.
Conclusion
The Measure Thickness tool is a powerful feature that helps you analyze your model for thin sections before printing. Whether you're using the fast Rays Method for simple models or the accurate Sphere Method for more complex internal structures, MeshInspector makes sure your 3D prints are successful and free from weak points.

FAQs
1. What is the Measure Thickness tool used for?
The Measure Thickness tool is used to identify thin areas in your 3D model that may cause issues during printing. It provides a color-coded map that highlights regions where the model’s thickness might be below the printer’s resolution limit, helping prevent weak points or failed prints.
2. What’s the difference between the Rays Method and the Sphere Method?
The Rays Method calculates thickness by projecting rays from the surface and measuring the distance between opposite sides, ideal for simpler geometries. The InSphere Method finds the largest sphere that can fit between two surfaces, making it more precise for complex internal structures or intricate models.
3. How do I prepare my model for accurate thickness measurements?
Ensure your model has enough vertices by remeshing or subdividing it if necessary. The Measure Thickness tool calculates based on vertex-to-surface distances, so models with more vertices will yield more precise results.
4. How can I fix areas that are too thin for 3D printing?
Once thin areas are identified using the Measure Thickness tool, you can use MeshInspector’s other tools, such as sculpting or remeshing, to adjust and repair those areas, ensuring your model is ready for printing.
5. Can I measure thickness in specific areas of the model?
Yes! You can click on any surface of the model to get a specific thickness measurement for that area, helping you focus on critical zones that may need attention.
