In this article, we'll explore the Offset tool in MeshInspector. Mesh offsetting involves creating a parallel surface at a specified distance from the original mesh, a feature crucial in industries like 3D printing, injection molding, and more, where precise control over surface thickness is needed. Let's dive into the different offset modes MeshInspector offers and their applications.
Overview of Offset Modes
1. Entire Model Offset Mode
Purpose: Uniformly offsets the entire mesh.
How It Works: A positive value pushes the mesh outward by the specified distance in millimeters, while a negative value pulls it inward.
2. Thickening Mode
Purpose: Creates an additional surface, effectively thickening your model.
How It Works: A positive value creates an additional layer outside the initial model, while a negative value creates it inside.
3. Shell Mode
Purpose: Creates two new surfaces in both directions and eliminates the initial mesh.
Use Case: Useful for creating a hollow part for mold making.
4. Expand/Shrink Mode
Purpose: Smooths concave features and increases the model volume.
How It Works: Expands the mesh by a set distance and then shrinks it, resulting in a smoothed surface.
5. Shrink/Expand Mode
Purpose: Smooths convex features and decreases the model volume.
How It Works: Shrinks the mesh by a set distance and then expands it, smoothing out noise or minor imperfections on complex surfaces.
Advanced Settings
Voxel Size: Controls the detail level of the created surface. A smaller voxel size provides more detail but may slow down performance.
Decimation: Simplifies the created surface by reducing the number of triangles. Keeping decimation on is generally advisable for better performance.

FAQ
Q1: What is the purpose of the Entire Model Offset mode?
The Entire Model Offset mode uniformly offsets the entire mesh. A positive value pushes the mesh outward, while a negative value pulls it inward.
Q2: How does the Thickening mode differ from the Entire Model Offset mode?
The Thickening mode creates an additional surface, effectively thickening your model, whereas the Entire Model Offset mode uniformly offsets the entire mesh.
Q3: When should I use Shell mode?
Shell mode is useful for creating a hollow part for mold making, as it creates two new surfaces in both directions and eliminates the initial mesh.
Q4: What is the difference between Expand/Shrink and Shrink/Expand modes?
Expand/Shrink mode first expands the mesh and then shrinks it, smoothing concave features and increasing the model volume. Shrink/Expand mode first shrinks and then expands the mesh, smoothing convex features and decreasing the model volume.
Q5: How can I control the detail level of the created surface?
You can adjust the voxel size in the advanced settings. A smaller voxel size gives more detail but may slow down performance. Keeping decimation on is advisable for better performance.
