<h1>Revolution</h1>

<p>Revolution 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 apply revolution:</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>Revolution </B></span>item
 or click <img src="image92.gif" width="24px" height="25px" 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="pics/revolution1.png" x-maintain-ratio="TRUE" width="390px" height="437px" border="0" class="img_whs3"><img src="pics/revolution2.png" x-maintain-ratio="TRUE" width="390px" height="437px" border="0" class="img_whs4"></p>

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

<p class="whs1">2. In this dialog box you should specify:</p>

<ul type="disc" class="whs5">

	<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 revolved 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 axis (point
 and vector) around which the elements will be revolved,</p></li>

	<li class=kadov-p><p class="whs1">angle of rotation,</p></li>

	<li class=kadov-p><p class="whs1">number of steps,</p></li>

	<li class=kadov-p><p class="whs1">tolerance of rotation</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>
