Automatically Fix Mesh Quality
The Auto Fix tool is useful for cleaning up non-manifold edges, free edges, intersections, high aspect ratio elements, and proximity distance.

                Select parts/elements to fix.
                Note: This tool is intended for cleaning up closed volumes, so only select parts that form a single closed volume.

- Fix intersecting elements.
- Aspect ratio
- Fix elements with aspect ratios above the defined value.
- Remesh size
- Remesh very bad elements with this size. This value should be the same as the average size defined when meshing selected parts.
- Proximity distance to smooth
- Smooth regions with proximity less than the defined value.
