\page convert_to_from_quadratic_mesh_page Convert to/from Quadratic Mesh
-\n This functionality allows you to transtorm standard meshes to
-quadratic and vice versa. See \ref adding_quadratic_elements_page "Adding quadratic elements"
+\n This functionality allows transforming standard meshes (or
+sub-meshes) to quadratic and vice versa.
+See \ref adding_quadratic_elements_page "Adding quadratic elements"
for more information about quadratic meshes.
+Note that conversion of a 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>From the Modification menu choose the Convert to/from Quadratic
-Mesh item, or click <em>"Convert to/from quadratic"</em> button in the
+<li>Select a mesh or a sub-mesh in the Object Browser or in the
+Viewer.</li>
+<li>From the Modification menu choose <b> Convert to/from Quadratic
+Mesh item </b>, or click <em>"Convert to/from quadratic"</em> button in the
toolbar.

<ul>
-<li>if you wish to convert standard mesh to quadratic or quadratic to standard;</li>
-<li>if you wish to place medium nodes of the quadratic mesh on the geometry (meshed object).</li>
+<li>if it is necessary to convert a standard mesh to quadratic or a quadratic
+mesh to standard. Note that the choice is available only if the selected mesh
+(or sub-mesh) contains both quadratic and linear elements, else the
+direction of conversion is selected automatically.</li>
+
+<li>if it is necessary to place medium nodes of the quadratic mesh on the
+geometry (meshed object). This option is relevant for conversion to
+quadratic provided that the mesh is based on a geometry (not imported from file).</li>
