Generator siatki
Oto dostępne generatory siatki i ich ustawienia:

Generator standardowy

 * : the maximum linear deviation of a mesh section from the surface of the object.
 * : the maximum angular deviation from one mesh section to the next. This setting is used when meshing curved surfaces.
 * : if checked, the maximum linear deviation of a mesh segment will be the specified multiplied by the length of the current mesh segment (edge).
 * : if checked, the mesh will get the face colors of the object.
 * : if checked, mesh segments will be grouped according to the colors of the object's faces. These groups will be exported for mesh output formats supporting this feature (the OBJ format for example).

Generator Mefisto

 * : the maximum edge length of the mesh. A smaller value results in a finer mesh. Specifying, or unchecking the checkbox, results in a very coarse mesh.
 * If you press the button the mesher will enter an estimated value for the . This value is not very reliable if multiple objects have been selected.

Generator Netgen

 * : select an options for the finesse of the mesh:
 * : for this option the following settings can be specified:
 * : a smaller value results in a finer mesh. The value must be in the -  range.
 * : a larger value results in a finer mesh. The value must be in the -  range.
 * : a larger value results in a finer mesh. The value must be in the -  range.
 * if checked, the surface shape will be optimized.
 * if checked, second order elements will be generated resulting in a finer mesh.
 * if checked, the mesh will preferably use quadrilateral faces.
 * : a larger value results in a finer mesh. The value must be in the -  range.
 * : a larger value results in a finer mesh. The value must be in the -  range.
 * if checked, the surface shape will be optimized.
 * if checked, second order elements will be generated resulting in a finer mesh.
 * if checked, the mesh will preferably use quadrilateral faces.

Generator Gmsh
Dla użytkowników systemu Linux: wymagany jest zewnętrzny moduł Gmsh.


 * : select a meshing option:
 * : a smaller value results in a finer mesh. Specify to have this size automatically determined.
 * : a smaller value results in a finer mesh. The value should be smaller than the . Specify to have this size automatically determined.
 * : seems to be unsupported at this time.
 * : press the button and browse to the  path.
 * If the meshing process takes too long you can press the button to abort it.
 * Press the button to remove the information in the text area.
 * : a smaller value results in a finer mesh. Specify to have this size automatically determined.
 * : a smaller value results in a finer mesh. The value should be smaller than the . Specify to have this size automatically determined.

Uwagi

 * This command is not restricted to objects created with the Part workbench. It can create a mesh from any object that has a shape including objects created with the PartDesign workbench.
 * The Std Export command can export shape objects directly to a mesh format.

Scripting

To create a mesh object from a shape object use the method of the MeshPart module. This method has several signatures. The signature determines the mesher that will be used. The example below uses the Mefisto mesher signature.
