Introduction

El Entorno de trabajo para mallas maneja triangle mesh. Las mallas son un tipo especial de objeto 3D, compuesto de triángulos conectados por sus bordes y sus esquinas (también llamados vértices).

Muchas aplicaciones 3D usan mallas como su objeto 3D básico, como sketchup, blender, maya o 3d studio max. Dado que las mallas son objetos muy simples, que contiene sólo los vértices (puntos), los bordes y las caras (triangulares), son muy fáciles de crear, modificar, dividir, estirar, y fácilmente se puede pasar de una aplicación a otra sin ningún tipo de pérdida. Además, ya que contienen datos muy sencillos, las aplicaciones 3D pueden manejar gran cantidad de mallas sin ningún problema. Por estas razones, las mallas son a menudo el tipo de objeto 3D de elección preferente en aplicaciones de tratamiento de películas, animación y creación de imágenes.

En el campo de la ingeniería, sin embargo, las mallas presentan una gran limitación: son objetos muy simples, solo compuestos de puntos, líneas y caras. Solo están hechos de superficies y no tienen información masiva, por lo que no se comportan como sólidos. En una malla no hay forma automática de saber si un punto está dentro o fuera del objeto. Esto significa que todas las operaciones basadas en sólidos, como la suma o la resta, siempre son un poco difíciles de realizar en las mallas, y retorna errores a menudo.

Usando el módulo de Malla

El módulo de malla tiene actualmente una interfaz muy simple, todas sus funciones están agrupadas en la entrada del menú Malla. Las operaciones más importantes que puede hacer actualmente con mallas son:

  • Close hole: Fills selected holes in mesh objects.
  • Add triangle: Adds faces along a boundary of an open mesh object.
  • Realiza operaciones ' Booleanas con mallas
    • Union: hace una unión (fusión) con mallas
    • Intersection: hace una intersección (común) en mallas
    • Difference: Hace una diferencia (corte) en mallas
  • Merge: Creates a mesh object by combining the meshes of two or more mesh objects.

Preferences

There are some export preferences related to Mesh Formats but these are not used by commands belonging to this workbench. They are used by the Std Export command.

Mesh Workbench preferences can be found in the following categories of the Preferences Editor:
