Mesh Analysis
Mesh analysis is useful for displaying attributes of the mesh that may impact certain use cases.
The mesh analysis works in editmode and shows areas with a high value in red, and areas with a low value in blue. Geometry outside the range is displayed grey.
Currently the different modes target 3d-printing as their primary use.
Overhang
Overhang
Extrusion 3D printers have a physical limit to the overhang that can be printed, this display mode shows the overhang with angle range and axis selection.
Thickness
Thickness
Printers have a limited wall-thickness where very thin areas can’t be printed, this test uses ray casting and a distance range to the thickness of the geometry.
Intersections
Intersecting faces
Another common cause of problems for printing are intersections between surfaces, where the inside/outside of a model can’t be reliably detected.
Unlike other display modes, intersections have no variance and are either on or off.
Distortion
Distorted Faces
Distorted geometry can cause problems since the triangulation of a distorted ngon is undefined.
Distortion is measured by faces which are not flat, with parts of the face pointing in different directions.
Sharp Edges
Sharp edges
Similar to wall-thickness, sharp edges can form shapes that are too thin to be able to print.
Warning
There are some known limitations with mesh analysis
Currently only displayed with deform modifiers.
For high-poly meshes is slow to use while editing the mesh.
