Mesh Workbench/hu

Introduction
A háló munkafelület háromszöghálókat kezel. A hálók különleges típusú 3D objektumok, amelyek a szélüknél és sarkaiknál kapcsolódó háromszögekből állnak (verticle néven is ismertek).

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.

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:
 * [[Image:Preferences-display.svg|32px]] Display: On the Mesh view tab several preferences can be set.
 * [[Image:Preferences-openscad.svg|32px]] OpenSCAD: The Mesh Union, Mesh Intersection and Mesh Difference commands require OpenSCAD and use the OpenSCAD executable preference to find its executable.
