\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:

+<br><center><h2>Extrusion of 2d face along a mesh builds on wire</h2></center>
-In this example the path mesh has been built on a wire (polyline with
-six edges). The first edge of the wire was used as <b>Shape (edge)</b>, node
-#1 as <b>Start node</b>. The angles have been defined as {10, 10, 10}. The
-middle edge (#4) of the initial mesh has been extruded.
+In this example the path mesh has been built on a wire contains 3
+edges. Node #1 is used as start node. Linear angle variation by 180
+degree is applied.

-This extrusion bases on the same path mesh as in the previous example
-but the third edge of the wire was set as <b>Shape (edge)</b> and node
-#4 as <b>Start node</b>. Please note, that the extrusion has been done
-in direction from node #4 to node #3, i.e. against the wire
-direction. In this example both faces of the initial mesh have been
-extruded.
