Le Mesh analysis est utile pour affiche les attributs du maillage, qui peuvent impacter certains cas d’utilisation.

The mesh analysis works in Edit Mode and Solid Viewport shading. It shows areas with a high value in red, and areas with a low value in blue. Geometry outside the range is displayed gray.

Currently the different modes target 3D-printing as their primary use.

Avertissement

il y a des limitations connues pour le Mesh analysis :

  • Currently only displayed with Deform Modifiers.
  • For high-poly meshes is slow to use while editing the mesh.

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.

Overhang.

Thickness

Printers have a limited wall-thickness where very thin areas cannot be printed, this test uses ray casting and a distance range to the thickness of the geometry.

Thickness.

Intersections

Une autre cause de problèmes pour l’impression sont les intersections entre surfaces, où l’intérieur/extérieur d’un modèle ne peuvent pas être détectés de manière fiable.

Unlike other display modes, intersections have no variance and are either on or off.

Intersecting faces.

Distortion

Distorted geometry can cause problems since the triangulation of a distorted n-gon is undefined.

La distortion est mesurée par les faces qui ne sont pas plates, avec des parties de la face pointant dans différentes directions.

Sharp Edges

Similar to wall-thickness, sharp edges can form shapes that are too thin to be able to print.
