-
-\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 (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>
-<li>In the standard <b>Search File</b> dialog box find the file for
- import. It is possible to select multiple files to be imported all at
- once. </li>
-
-<li>Click the \b OK button.</li>
-</ol>

-<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
- exported file and enter its name.</li>
- <li>Click the \b OK button.</li>

- 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>
