+<h2>Editing the mesh</h2>
+
+It is possible to \ref modifying_meshes_page "edit the mesh" of
+lower dimension before generation of mesh of higher dimension.
+
+For example you can generate 2D mesh, modify it using e.g.
+\ref pattern_mapping_page, and then generate 3D mesh basing on the
+modified 2D mesh. The workflow is following:
+- Define 1D and 2D meshing algorithms.
+- Compute the mesh. 2D mesh is generated.
+- Apply \ref pattern_mapping_page.
+- Define 3D meshing algorithms without modifying 1D and 2D algorithms
+and hypotheses.
+- Compute the mesh. 3D mesh is generated.
