<p>To create a <span style="font-weight: bold;"><B>Point</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; Point</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 </font></span><span style="font-size: 12pt; font-weight: bold;"><font size=3 style="font-size:12pt;"><B>Point</B></font></span><span 
 style="font-size: 12pt;"><font size=3 style="font-size:12pt;"> in the 3D space.</font></span></p>

<p class="whs2"><b style="font-weight: bold;"><span style="font-weight: normal;">Each 
 time the</span> Result <span style="font-weight: normal;">of the operation 
 will be a</span></b> GEOM_Object (vertex).</p>

<p class="whs2">&nbsp;</p>

<p class="whs2"><b style="font-weight: bold;"><span style="font-weight: normal;">Firstly, 
 we can define a point by setting its X, Y and Z </span><span style="font-weight: bold;"><B>C</B></span></b><b><span 
 style="font-weight: bold;"><B>oordinates</B></span><span style="font-weight: normal;">.</span>

<p class="whs2"><b style="font-weight: bold;">Arguments: </b>Name 
 <b><span style="font-weight: normal;">(Vertex_n by default) </span></b>+ 
 X, Y and Z coordinates of the point.</p>

<p class="whs2">&nbsp;</p>

<p class="whs2">Secondly, &nbsp;we 
 can define a point by a <span style="font-weight: bold;"><B>Reference</B></span> 
 to another point and the shift of the coordinates of the new point regarding 
 the coordinates of the old one. </p>

<p class="whs2"><b style="font-weight: bold;">TUI Command :</b> 
 &nbsp;&nbsp;<span style="font-style: italic;"><I>geompy.MakeVertexWithRef(Reference,

<p class="whs2"><b style="font-weight: bold;">Arguments: </b>Name

 regarding the reference one.</p>

<p class="whs6">&nbsp;</p>

<p class="whs7">Finally, we can define a 
 point by an <span style="font-weight: bold;"><B>Edge</B></span> and a <span style="font-weight: bold;"><B>Parameter</B></span> 
 &nbsp;indicating 
 its position on the Edge. For example, 0.5 means that the point is located 
 in the middle of the edge.<span style="font-style: italic;"> <I></I></span></p>

<p class="whs8"><span style="font-style: italic;"><I><b style="font-weight: bold; font-style: normal;">TUI
