<h1><span style="font-size: 12pt;"><font size=3 style="font-size:12pt;"><img src="image35.gif" width="16px" height="16px" border="0" class="img_whs1"></font></span>Local Coordinate 
 System</h1>

<p>To create a <span style="font-weight: bold;"><B>Local Coordinate System</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; Local Coordinate 
 System</B></span></p>

<p class="whs2">There are three algorithms to choose from.</p>

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

<p class="whs2">Firstly, you can define the values of X, Y, 
 and Z coordinates of origin and the directions of X and Y axes directly 
 in the menu.</p>

<p class="whs2"><span style="font-weight: bold;"><B>TUI command:</B></span> 
 <span style="font-style: italic;"><I>geompy.MakeMarker(OX, OY, OZ, XDX, XDY, 
 XDZ, YDX, YDY, YDZ)</I></span>, where OX, OY, OZ are coordinates of the origin 
 of LCS, XDX, XDY, XDZ is a vector of OX &nbsp;direction 
 of the LCS and YDX, YDY, YDZ is a a vector of OY direction of the LCS.</p>

<p class="whs2"><b style="font-weight: bold;">Arguments:</b> 
 Name + Coordinates of origin, X axis direction, Y axis direction.</p>

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

<p class="whs3"><img src="pics/neo-localcs1.png" x-maintain-ratio="TRUE" width="312px" height="391px" border="0" class="img_whs4"></p>

<p class="whs5">&nbsp;</p>

<p class="whs6">Secondly, you can simply 
 select a point in the object browser or 3D viewer, in this case the coordinates 
 of origin are automatically filled in with the coordinates of the selected 
 point and X and Y axes direction will be parallel to the X and Y direction 
 of the Global CS. &nbsp;</p>

<p class="whs6"><b style="font-weight: bold;">Arguments: 
 </b>Name + reference object.</p>

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

<p class="whs3"><img src="pics/neo-localcs2.png" x-maintain-ratio="TRUE" width="312px" height="289px" border="0" class="img_whs7"></p>

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

<p class="whs2">The last algorithm also presumes that you select 
 a point in the object browser or 3D viewer, but in this case you define 
 X and Y axes direction yourselves. </p>

<p class="whs8"><b style="font-weight: bold;">Arguments:</b> 
 <span style="font-weight: normal;">Name + 1 point of origin + X axis direction, 
 Y axis direction.</span></p>

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

<p class="whs3"><img src="pics/neo-localcs3.png" x-maintain-ratio="TRUE" width="312px" height="359px" border="0" class="img_whs9"></p>

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

<p class="whs2">Press �OK� or �Apply� button to create an LCS 
 at the location with the specified coordinates. The new object is shown 
 in the Object Browser and in 3D viewer.</p>

<p class="whs10">&nbsp;</p>

<p class="whs11">Example:</p>

<p class="whs12"><img src="image145.jpg" width="200px" height="219px" border="0" class="img_whs13"></p>

<p class="whs12">&nbsp;</p>
