-Viewing meshes
-**************
-
-By default a just :ref:`computed <compute_anchor>` mesh will be
-automatically displayed in the **VTK 3D Viewer**. (You can switch
-off :ref:`Automatic Update <automatic_update_pref>` preference parameter
-to prevent this.)
-Click **Display only** to hide all other objects at the same time.
-
-**VTK 3D Viewer** is described in detail in the documentation on **GUI module**.
-
-Use the following :ref:`preference parameters <mesh_preferences_page>`
-to adjust how the mesh is displayed by default:
-
-* :ref:`Automatic Update <automatic_update_pref>`
-* :ref:`Default display mode <display_mode_pref>`
-* :ref:`Representation of the 2D quadratic elements <quadratic_2d_mode_pref>`
-* All parameters of :ref:`Mesh <mesh_tab_preferences>` tab page of Preferences dialog.
-
-After the mesh has appeared in the Viewer, you can select it with
-left mouse click and get information about it, change its
-presentation parameters and access to other useful options by
-right-clicking on the selected mesh.

-
-* **Rename** - allows to rename the object in the Object browser.
-* **Hide all** - allows to hide all objects in the viewer.
-* **Update** - refreshes the presentation of your mesh in the 3D Viewer, applying all recent changes.
-* :ref:`Mesh Information <mesh_infos_page>` - provides information about the mesh.
-* :ref:`Find Element by Point <find_element_by_point_page>` - allows to find all mesh elements, to which belongs a point with the given coordinates.
-* **Auto Color** - switch on / off auto-assigning colors for the groups. If switched on, a default color of a new group in :ref:`Create Group <creating_groups_page>` dialog is chosen randomly.
-* :ref:`Numbering <numbering_page>` - allows to display the ID numbers of all meshing elements or nodes composing your mesh in the viewer.
-* :ref:`Display Mode <display_mode_page>` - allows to select between Wireframe, Shading and Nodes presentation.
-* :ref:`Display Entity <display_entity_page>` - allows to display entities by types (Faces, Edges, Volumes etc.).
-
-.. _quadratic_2d_mode:
-
-* **2D Quadratic** - allows to select between the representation of quadratic edges as broken **lines** or as **arcs**. A default representation can be set in :ref:`Preferences <quadratic_2d_mode_pref>`. Arc representation applies to 1D and 2D elements only.
-* **Orientation of faces** - shows vectors of orientation of faces of the selected mesh. The orientation vector is shown for each 2D mesh element and for each free facet of a 3D mesh element. The vector direction is calculated by the first three nodes of the face produced by vectors n1-n2 and n1-n3.
-* :ref:`Properties <colors_size_page>` - allows to define several visual properties, including color of elements, shrink size, ...
-* :ref:`Transparency <transparency_page>` - allows to change the transparency of mesh elements.
-* :ref:`Controls <quality_page>` - graphically presents various information about the mesh.
-* **Hide** - allows to hide the selected mesh from the viewer.
-* **Show Only** - allows to display only the selected mesh, hiding all others from the viewer. If :ref:`Fit All upon Show Only <display_mode_pref>` Preference option is active, *Fit All* command is additionally performed.
-* :doc:`clipping` - allows to create cross-sections of the displayed objects.
-* **Dump view** - exports an object from the viewer in bmp, png or jpeg image format.
-* **Change background** - allows to redefine the background color. By default it is black.
-* **View Operations** - allows to show/hide the visualization toolbar in the Viewer window.
-* **Recording Operations** - allows to show/hide the recording toolbar in the Viewer window.
