\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.

The following dialog common for line and planar elements will appear:

|
|
|
|
</li>
|
|
|
|
<li>In this dialog:
|
|
<ul>
|
|
<li>select the type of elements which will be extruded (0D, 1D or 2D),</li>
|
|
<li>specify the IDs of the elements which will be extruded:
|
|
<ul>
|
|
<li><b>Select the whole mesh, submesh or group</b> activating this
|
|
checkbox; or</li>
|
|
<li>choose mesh elements with the mouse in the 3D Viewer. It is
|
|
possible to select a whole area with a mouse frame; or</li>
|
|
<li>input the element IDs directly in <b>ID Elements</b> field. The selected elements will be highlighted in the
|
|
viewer; or</li>
|
|
<li>apply Filters. <b>Set filter</b> button allows to apply a filter to the selection of elements. See more
|
|
about filters in the \ref selection_filter_library_page "Selection filter library" page.</li>
|
|
</ul>
|
|
</li>
|
|
<li>If the <b>Extrude to Distance</b> radio button is selected</li>
|
|
<ul>
|
|
<li>specify the distance at which the elements will be extruded,</li>
|
|
</ul>
|
|
<li>If the <b>Extrude Along Vector</b> radio button is selected</li>
|
|
<ul>
|
|
<li>specify the coordinates of the vector along which the elements will be extruded, or select the face (the normal to the face will define the vector)</li>
|
|
<li>specify the distance of extrusion along the vector,</li>
|
|
</ul>
|
|
<li>specify the number of steps;</li>
|
|
<li>activate <b>Generate Groups</b> checkbox if it is necessary to copy the groups of
|
|
elements of the source mesh to the newly created one. </li>
|
|
</li>
|
|
</ul>
|
|
|
|
<li>Click \b Apply or <b> Apply and Close</b> button to confirm the operation.</li>

</ol>
