<h1>Uniting two triangles</h1>

<p>&nbsp;In MESH 
 you can union two neighboring triangles (cells) by deletion of the common 
 edge.</p>

<p>&nbsp;</p>

<p class=TODO>To unite two triangles:</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>Union of two triangles 
 </B></span>item or click <img src="../image71.gif" width="23px" height="23px" 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/unionoftwotriangles.png" x-maintain-ratio="TRUE" width="306px" height="163px" border="0" class="img_whs3"></p>

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

<p class="whs1">2. Enter the ID of the required edge in the 
 <span style="font-weight: bold;"><B>Edge </B></span>&nbsp;field 
 or select this edge in the 3D viewer. </p>

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

<p class="whs1">3. Click the <span style="font-weight: bold;"><B>Apply
