 \n In principle, <b>Extrusion along a path</b> works in the same way
 as \b Extrusion, the main difference is that we define not a vector,
-but a path of extrusion which must be a meshed edge. To get an idea of
-how this algorithm works, examine several examples, starting from the
-most simple case of extrusion along a straight edge. In all examples
-the same mesh will be extruded along different paths and with
-different parameters. This sample 2D mesh has two quadrangle faces and
-seven edges. Look at the picture, where white digits are the node
-numbers and green are the element numbers:
