+Alternatively you can orient all 2D cells equally using the first cell as a reference:

+   :start-after: UG_CommonHandlingMesh_11_1
+   :end-before:  UG_CommonHandlingMesh_11_1

+Also it is possible to orient some selected 2D cells by using another group of cells as the reference:

+   :start-after: UG_CommonHandlingMesh_11_2

 If your mesh includes incorrectly oriented polyhedra, the following method can help to fix your mesh:
