+\n This functionality allows you to transtorm standard meshes (or
+sum-mesh) to quadratic and vice versa.
+See \ref adding_quadratic_elements_page "Adding quadratic elements"
for more information about quadratic meshes.
+Note that conversion of the sub-mesh most probably will
+produce a non-conformal mesh. Elements on the boundary between
+quadratic and linear sub-meshes become (or remain) quadratic.
<em>To produce a conversion:</em>
<ol>
+<li>Select a mesh or a sub-mesh in the Object Browser or in the
+Viewer.</li>
<li>From the Modification menu choose the Convert to/from Quadratic
Mesh item, or click <em>"Convert to/from quadratic"</em> button in the
toolbar.

+<li>if you wish to convert a standard mesh to quadratic or a quadratic

+(or sub-mesh) contains both quadratic and linear elements, else the

+qudratic mesh only and provided that the mesh is based on some
+geometry (not imported from the file).</li>
