automatically generate a 3D mesh with the most appropriate
settings. In the same way you can apply this functionality for meshing
2D objects, in which case 3D algorithms are not applied.</li>
-<li>Now, when everything is ready, select your mesh in the <b>Object
+
+<li> After the mesh object is created and all hypotheses are assigned and
+before the mesh computation, it is possible to see the mesh preview.
+
+For this, select the mesh in the Object Browser. From the \b Mesh menu
+select \b Preview or click "Preview" button in the
+toolbar or activate "Preview" item from the pop-up menu.

+When the Preview dialog is closed, the question about the storage of temporarily
+created mesh elements appers:

+These elenents can be reused in the next mesh computation.

+
+
+<li>It is equally possible to skip the Preview and \b Compute the mesh
+after the hypotheses are assigned. For this, select your mesh in the <b>Object
Browser</b>. From the \b Mesh menu select \b Compute or click "Compute" button of the
toolbar.
