<h1>Extrusion</h1>
<p>Extrusion is a type of surface meshing by generation from discretized
lines. It is used to build mesh elements of plus one dimension than the
swept ones. Each swept 1D element produces one or more quadrangles (or
triangles if one node of a rotated element lays on the revolution axis).</p>
<p>&nbsp;</p>
<p class=TODO>To use extrusion:</p>
<p class=TODO>&nbsp;</p>
<p class="whs1">1. From the <span style="font-weight: bold;"><B>Modification
</B></span>menu choose the <span style="font-weight: bold;"><B>Extrusion </B></span>item
or click <img src="image91.gif" width="27px" height="24px" border="0" class="img_whs2"> button in the toolbar. The following dialog box
shall appear:</p>
<p class="whs1">&nbsp;</p>
<p class="whs1"><img src="image90.gif" width="523px" height="307px" border="0" class="img_whs3"></p>
<p class="whs1">&nbsp;</p>
<p class="whs1">2. In this dialog box you should select </p>
<ul type="disc" class="whs4">
<li class=kadov-p><p class="whs1">the type of elements
which will be extruded (1D or 2D),</p></li>
<li class=kadov-p><p class="whs1">specify the IDs of
the elements which will be extruded by selecting them in the 3D viewer
or select the whole mesh or submesh,</p></li>
<li class=kadov-p><p class="whs1">specify the vector
along which the elements will be extruded,</p></li>
<li class=kadov-p><p class="whs1">number of steps</p></li>
</ul>
<p class="whs1">&nbsp;</p>
<p class="whs1">3. Click the <span style="font-weight: bold;"><B>Apply
</B></span>or <span style="font-weight: bold;"><B>OK </B></span>button.</p>
