<p>Definition of a <span style="font-weight: bold;"><B>Working Plane</B></span>
is necessary for work with <span style="font-weight: bold;"><B><a href="sketcher.htm">Sketcher</a></B></span>.
</p>
<p> </p>
<p>To create a <span style="font-weight: bold;"><B>Working Plane</B></span> in
the <span style="font-weight: bold;"><B>Main Menu</B></span> select <span style="font-weight: bold;"><B>New
Entity - > Basic - > Working Plane</B></span></p>
<p class="whs2"> </p>
<p class="whs2">There is a number of algorithms to set the
<span style="font-weight: bold;"><B>Working Plane</B></span> and the Camera Position.</p>
<p class="whs2"> </p>
<p class="whs2">Firstly, you can select a <span style="font-weight: bold;"><B>Plane</B></span>,<span
style="font-weight: bold;"> <B></B></span>a <span style="font-weight: bold;"><B>Planar
Face</B></span> or a <span style="font-weight: bold;"><B>Local Coordinate System</B></span>
to be your <span style="font-weight: bold;"><B>Working Plane</B></span></p>
<p class="whs2"><b style="font-weight: bold;">Arguments:</b>
Name + 1 selection (face or planar face), </p>

<p class="whs2"> </p>
<p class="whs2">Secondly, you can define a <span style="font-weight: bold;"><B>Working
Plane</B></span> by two <span style="font-weight: bold;"><B>Vectors</B></span></p>
<p class="whs2"><b style="font-weight: bold;">Arguments:</b>

vectors.</p>

<p class="whs2"> </p>
<p class="whs2">Finally, you can select one of three basic
projections of XYZ coordinate system to be your <span style="font-weight: bold;"><B>Working
Plane</B></span></p>
