\page extrusion_page Extrusion
|
|
|
|
\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.
|
|
|
|
<em>To use extrusion:</em>
|
|
<ol>
|
|
<li>From the \b Modification menu choose the \b Extrusion item or click
|
|
<em>"Extrusion"</em> button in the toolbar.

</li>
|
|
|
|
<li>In this dialog box you should select:
|
|
<ul>
|
|
<li>the type of elements which will be extruded (1D or 2D),</li>
|
|
<li>specify the IDs of the elements which will be extruded by
|
|
selecting them in the 3D viewer or select the whole mesh or
|
|
submesh,
|
|
<ul>
|
|
<li>Check on <b>Select the whole mesh, submesh or group</b> option
|
|
<li>Choosing them manually with the mouse in the 3D Viewer. You can
|

click on an element in the 3D viewer and it will be highlighted</li>
|
|
<li>Applying Filters. The <b>Set filter</b> button allows to apply a

|
about filters on the

\ref selection_filter_library_page "Selection filter library" page.</li>
|
|
</ul>
|
|
</li>
|
|
<li>specify the distance at which the elements will be extruded,</li>
|
|
<li>specify the vector along which the elements will be extruded,</li>
|
|
<li>number of steps.</li>
|
|
</ul>
|
|
<li> <b>Generate Groups</b> checkbox allows copying the groups of
|
|
elements of the source mesh to the newly created one. </li>

</li>
|
|
|
|
<li>Click the \b Apply or \b OK button.</li>
