<p>There are 2 algorithms for creation of <span style="font-size: 12pt;"><font size=3 style="font-size:12pt;">an 
 Extrusion (Prism)</font></span>. </p>

<p class="whs2">Firstly, you can define the <span style="font-weight: bold;"><B>Base 
 Shape </B></span>(a basis of the extrusion)<span style="font-weight: bold;"><B>, 
 </B></span>the <span style="font-weight: bold;"><B>Vector</B></span> (a direction 
 of the extrusion) and the <span style="font-weight: bold;"><B>Height</B></span> 
 of extrusion. &nbsp;</p>

<p class="whs2"><b style="font-weight: bold;"><span style="font-weight: normal;">The</span> 
 Result <span style="font-weight: normal;">of the operation will be a</span></b> 
 GEOM_Object (edge, face, solid or compsolid).</p>

 Command :</b><i> </i></B></span><span style="font-style: italic;"><I>geompy.MakePrismVecH(Base,

<p class="whs2"><span style="font-size: 12pt;"><font size=3 style="font-size:12pt;"><b style="font-weight: bold;">Arguments:</b> 
 Name + 1 shape (vertex, edge, wire, face or shell) serving as base object

<p class="whs5"><span style="font-weight: normal;">Secondly, 
 you can define the</span> Extrusion <span style="font-weight: normal;">by

 of the </span>Vector<span style="font-weight: normal;"> &nbsp;(in
