<p>To create a <span style="font-weight: bold;"><B>Plane</B></span> in the <span
style="font-weight: bold;"><B>Main Menu</B></span> select <span style="font-weight: bold;"><B>New
Entity - &gt; Basic - &gt; Plane</B></span></p>
<p>&nbsp;</p>
<p>There are three algorithms to <span style="font-size: 12pt;"><font size=3 style="font-size:12pt;">create
a point in the 3D space.</font></span></p>
<p><b style="font-weight: bold;"><span style="font-weight: normal;">The</span><span
style="font-size: 12pt;"><font size=3 style="font-size:12pt;"> Result </font></span><span style="font-weight: normal;">of
each operation will be a</span></b><span style="font-size: 12pt;"><font size=3 style="font-size:12pt;"> GEOM_Object
(face).</font></span></p>
<p class="whs2">&nbsp;</p>
<p class="whs2">Firstly, you can define a <span style="font-weight: bold;"><B>Plane</B></span>
by a <span style="font-weight: bold;"><B>Point </B></span>through which &nbsp;the
plane passes, a <span style="font-weight: bold;"><B>Vector </B></span>giving
a normal of the plane and a <span style="font-weight: bold;"><B>Size of the
Plane</B></span> (size of a side of quadrangle face, representing the plane).</p>
<p class="whs2"><span style="font-weight: bold;"><B><b style="font-weight: bold;">TUI
Command:</b> </B></span><span style="font-style: italic;"><I>geompy.MakePlane(Point,
Vector, TrimSize)</I></span></p>
<p class="whs2"><b style="font-weight: bold;">Arguments: </b>Name
+ 1 vertex + 1 vector &nbsp;+
1 value (to define the size of the plane).</p>
<p class="whs2"><b style="font-weight: bold;"><img src="pics/plane1.png" x-maintain-ratio="TRUE" width="312px" height="346px" border="0" class="img_whs3"></b></p>
<p class="whs2">&nbsp;</p>
<p class="whs2">Secondly, you can define a <span style="font-weight: bold;"><B>Plane</B></span>
by three <span style="font-weight: bold;"><B>Points </B></span>through which
&nbsp;the plane
passes.</p>
<p class="whs4"><b style="font-weight: bold;">TUI
Command:</b> <span style="font-weight: normal; font-style: italic;"><I>geompy.MakePlaneThreePnt(Point1,
Point2, Point3, TrimSize)</I></span> </p>
<p class="whs4"><b style="font-weight: bold;">Arguments:

the direction) + 1 value (to define the size of the plane).</span></p>

<p class="whs2"><img src="pics/plane2.png" x-maintain-ratio="TRUE" width="312px" height="385px" border="0" class="img_whs5"></p>
<p class="whs2">&nbsp;</p>
<p class="whs2">Finally, you can define a <span style="font-weight: bold;"><B>Plane</B></span>,
similar to the existing one, but with another size of representing face.

<p class="whs2"><span style="font-weight: bold;"><B><b style="font-weight: bold;">TUI
