 \n Extrusion is used to build mesh elements of plus one
-dimension than the input ones. Any line or planar element can be
-extruded. Line elements will extrude into quadrilateral plane elements.
-Triangular and Quadrilateral plane elements extrude into Pentahedron
-and Hexahedron solids respectively.
+dimension than the input ones. Boundary elements around elements of
+plus one dimension are additionally created. All created elements
+can be automatically grouped.
+<p>Any node, segment or 2D element can be extruded. Each type of
+elements is extruded into a corresponding type of result elements:
