+\n In MESH there is a functionality allowing import/export
of meshes from/to \b MED, \b UNV (I-DEAS 10), \b DAT (simple ascii format), \b STL,
-\b GMF and \b CGNS format files. You can also export a group as a whole mesh.
+\b GMF (internal format of DISTENE products, namely MG-CADSurf, MG-Tetra and
+MG-Hexa algorithms) and \b CGNS format files. You can also export a
+group as a whole mesh.
<em>To import a mesh:</em>
<ol>
<li>From the \b File menu choose the \b Import item, from its sub-menu
-select the corresponding format (MED, UNV, STL, GMF and CGNS) of the file containing
-your mesh.</li>
+ select the corresponding format (MED, UNV, STL, GMF and CGNS) of the
+ file containing your mesh.</li>
<li>In the standard <b>Search File</b> dialog box find the file for
-importation. It is possible to select multiple files to be imported all at once. </li>

<em>To export a mesh or a group:</em>
<ol>
-<li>Select the object you wish to export.</li>
-<li>From the \b File menu choose the \b Export item, from its sub-menu
-select the format (MED, UNV, DAT, STL, GMF and CGNS) of the file which will
-contain your exported mesh.</li>
-<li>In the standard <b>Search File</b> select a location for the

\image html meshexportmesh.png
+ If you try to export a group, the warning will be shown:
+\image html meshexportgroupwarning.png
+<ul>
+ <li><b>Don't show this warning anymore</b> check-box allows to
+ switch off the warning. You can re-activate the warning in
+ \ref group_export_warning_pref "Preferences".</li>
+</ul>
+
+ There are additional parameters available at export to MED and SAUV format files.
+<ul>
+ <li>
+\anchor export_auto_groups
+ <b>Automatically create groups</b> check-box specifies whether to
+ create groups of all mesh entities of available dimensions or
+ not. The created groups have names like "Group_On_All_Nodes",
+ "Group_On_All_Faces", etc. A default state of this check-box can be
+ set in \ref export_auto_groups_pref "Preferences". </li>
+ <li><b>Automatically define space dimension</b> check-box specifies
+ whether to define space dimension for export by mesh configuration
+ or not. Usually the mesh is exported as a mesh in 3D space, just as
+ it is in Mesh module. The mesh can be exported as a mesh of a lower
+ dimension in the following cases, provided that this check-box is checked:
+ <ul>
+ <li> <b>1D</b>: if all mesh nodes lie on OX coordinate axis. </li>
+ <li> <b>2D</b>: if all mesh nodes lie in XOY coordinate plane. </li>
+ </ul>
+ </li>
+</ul>
