+At export to MED and SAUV format files additional parameters are available.
+<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 in lower
+ dimension in following cases, provided that this check-box is
+ checked.
+ <ul>
+ <li> 1D: if all mesh nodes lie on OX coordinate axis. </li>
+ <li> 2D: if all mesh nodes lie on XOY coordinate plane. </li>
+ </ul>
