Introdução

A Bancada de Malhas manipula malhas triangulares. As malhas são um tipo especial de objeto 3D, composto de faces triangulares conectadas por seus vértices e arestas.

Muitos aplicativos 3D, como Sketchup, Blender, .org / wiki / Maya_ (software) Maya e 3D Studio Max, usam malhas como seu tipo principal de objeto 3D. Como as malhas são objetos muito simples, contendo apenas vértices (pontos), arestas e faces triangulares, elas são muito fáceis de criar, modificar, subdividir, estender e podem ser facilmente passadas de um aplicativo para outro sem qualquer perda de detalhes. Além disso, como as malhas contêm dados muito simples, os aplicativos 3D geralmente podem gerenciar grandes quantidades deles sem usar muitos recursos. Por esses motivos, as malhas são geralmente o tipo de objeto 3D escolhido para aplicativos que lidam com filmes, animações e criação de imagens.

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

The Mesh Workbench has a simple interface; all its functions are grouped in the Mesh menu.

General tools

Analyze

Analysis of curvature, faces, and check if a mesh can be safely converted into a solid

Regular solid

Regular solid... Create mesh primitives, like cubes, cylinders, cones, or spheres:

Boolean

  • Union: Does a union (fusion) on meshes
  • Intersection: Does an intersection (common) on meshes
  • Difference: Does a difference (cut) on meshes

Cutting

Other

Preferences

More mesh tools are available in the OpenSCAD Workbench.

Meshes can also be handled by Mesh Scripting.
