<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 
 will appear:</p>

<p class="whs1">&nbsp;</p>

<p class="whs1"><img src="pics/extrusionalongaline1.png" x-maintain-ratio="TRUE" width="411px" height="309px" border="0" class="img_whs3"> &nbsp;<img src="pics/extrusionalongaline2.png" x-maintain-ratio="TRUE" width="411px" height="309px" 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>
