\page extrusion_along_path_page Extrusion along Path
\n In principle, <b>Extrusion along Path</b> works in the same way
-as \ref extrusion_page "Extrusion", the main difference is that we define not a vector,
-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 the examples the sample mesh will be extruded along different
mesh.</center>

<br><em>To use Extrusion along Path:</em>
<ol>
of following means:
<ul>
<li><b>Select the whole mesh, sub-mesh or group</b> activating this
- checkbox.</li>
+ check-box.</li>
<li>Choose mesh elements with the mouse in the 3D Viewer. It is
possible to select a whole area with a mouse frame.</li>
<li>Input the element IDs directly in <b>Node IDs</b>, <b>Edge
<li>Define the \b Path along which the elements will be extruded.<br>
Path definition consists of several elements:
<ul>
- <li><b>Mesh or submesh</b> - 1D mesh or sub-mesh, along which
+ <li><b>Mesh or sub-mesh</b> - 1D mesh or sub-mesh, along which
proceeds the extrusion.</li>
- <li><b>Start node</b> - the start node. It is used to define
- the direction of extrusion. </li>
+ <li><b>Start node</b> - the start node of the Path. It is used
+ to define the direction of extrusion. </li>
</ul>
</li>
<li>If you activate <b>Generate Groups</b> check-box, the <em>result elements</em>
