Introduction

The Mesh Workbench handles triangle meshes. Meshes are a special type of 3D object, composed of triangular faces connected by their vertices and edges.

Many 3D applications, like Sketchup, Blender, Maya and 3D Studio Max, use meshes as their primary type of 3D object. Since meshes are very simple objects, containing only vertices (points), edges and triangular faces, they are very easy to create, modify, subdivide, stretch, and can easily be passed from one application to another without any loss of details. In addition, since meshes contain very simple data, 3D applications can usually manage very large quantities of them without using a lot of resources. For these reasons, meshes are often the 3D object type of choice for applications dealing with movies, animation, and image creation.

However, in the field of engineering meshes present one big limitation: they are only made of surfaces, and have no mass information, so they don't behave as solids. This means that all solid-based operations, such as addition or subtraction, are difficult to perform on meshes. The Mesh Workbench is useful to import 3D data in mesh format, to analyse it, detect errors, and finally convert it to a solid, for use with the Part Workbench.

Tools

All Mesh Workbench tools can be accessed from the Meshes menu. Some tools are also available in the Mesh tools toolbar.

  • Close hole: Interactively closes holes in a mesh.
  • Boolean
    • Union: Does a union (fusion) on meshes.
    • Intersection: Does an intersection (common) on meshes.
    • Difference: Does a difference (cut) on meshes.

Preferences

More mesh tools are available in the OpenSCAD Workbench.

Meshes can also be handled via Python using Mesh Scripting.
