+\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 BLSurf, GHS3D and
+Hexotic 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 and DAT) 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.</li>
+ import. It is possible to select multiple files to be imported all at
+ once. </li>

<li>Click the \b OK button.</li>

+ There are additional parameters available at export to MED and SAUV format files.
+<ul>
+ <li><b>Automatically create groups</b> check-box specifies whether to
+ create groups of all mesh entities of available dimensions or
+ not. If checked, the created groups have names like "Group_On_All_Nodes",
+ "Group_On_All_Faces", etc.</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>
