\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:
but a path of extrusion which must be a 1D mesh or 1D sub-mesh. 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 following examples the meshes will be extruded along different
paths and with different parameters.
This sample 2D mesh has two quadrangle faces and seven edges. Look

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

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.
