<em>To apply symmetry to your mesh:</em>
\par
From the \b Modification choose \b Transformation and from its
<li>one plane (point and normal)</li>
</ul>
+<ul>
+<li>Select elements for the symmetry operation
+<ul>
+<li>Check on <b>Select the whole mesh, submesh or group</b> option
+<li>Choosing them manually with the mouse in the 3D Viewer. You can
+click on an element in the 3D viewer and it will be highlighted</li>
+<li>Applying Filters. The <b>Set filter</b> button allows to apply a

+<li>When <b>Move elements</b> radio button is selected, the source mesh (or elements) is created at the new location and erased from its previous location</li>
+<li>When <b>Copy elements</b> radio button is selected,the source mesh (or elements) is created at the new location, but it also remains at its previous location and is considered one and single mesh with the result of the translation.</li>
+<li>When <b>Create as new mesh</b> radio button is selected, the source mesh (or elements) remains at its previous location and a new mesh is created at the new location and appears in the Object Browser with the default name MeshName_mirrored (you can change this name in the adjacent box).</li>
+<li><b> Copy groups </b> checkbox allows copying the groups of elements of the source mesh to the newly created one.</li>
