I have used a number of different methods over the years. I am wondering if ZWCAD has an easier method than any of these ways I have bisectored angles in other CAD packages?</B></P> <P><B>Method A: Using Construction Lines to Bisect Angles</B></P> <P>This method is simple, but I have to trim away unwanted parts of the construction line: </P> <P>&nbsp;&nbsp; 1.&nbsp;Start the <B>XLine</B> command, or click the Construction Line icon.</P> <P>&nbsp;&nbsp; 2.&nbsp;Enter <B>B</B> for the Bisect option.</P> <P>&nbsp;&nbsp;&nbsp;3.&nbsp;Choose the vertex of the angle.</P> <P>&nbsp;&nbsp;&nbsp;4.&nbsp;Snap to the start and end points of the bisection angle.</P> <P><B>Method B: Using Angular Dimensions</B></P> <P>This method is practical, but I have to create an assistant angular dimension and then delete it after finishing the bisection of the angle:</P> <P>&nbsp; &nbsp;1.&nbsp;&nbsp;Start the <B>DimAngular</B> command, which creates angular dimensions between two sides of an angle. (The value of the angle is not important.) </P> <P>&nbsp;&nbsp; 2.&nbsp;&nbsp;Draw a line by specifying the following two points as the start and end points: </P> <P>·&nbsp;the vertex of the angle </P> <P>·&nbsp;the midpoint of the angular dimension.</P> <P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This line becomes the bisector of the angle.</P> <P>&nbsp;&nbsp; 3.&nbsp;&nbsp;Delete the angular dimension.</P> <P><B>Method C: Using Circles</B></P> <P>This method is similar to the second method but a little more complex:</P> <P>&nbsp;&nbsp;&nbsp;1.&nbsp;&nbsp;Draw a circle, and then specify its centerpoint at the vertex of the angle.</P> <P>&nbsp;&nbsp;&nbsp;2.&nbsp;&nbsp;Intersect the circle with the two sides of the angle.</P> <P>&nbsp;&nbsp;&nbsp;3.&nbsp;&nbsp;Trim off the part of the circle that are inside the angle.</P> <P>&nbsp;&nbsp;&nbsp;4.&nbsp;&nbsp;Construct a line by specifying these two points as the start and end points: </P> <P>·&nbsp;&nbsp;Vertex of the angle.</P> <P>·&nbsp;&nbsp;&nbsp;Midpoint of the reserve part of the circle. </P> <P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The line becomes the bisector of the angle.</P> <P><B>A:</B> ZWCAD has a special command just for bisecting angles, which is simpler to use than the methods you described above. I like this function because it is simple to draw a bisector of angle, and its saves me time. Here is how it works:&nbsp; </P> <P>&nbsp;&nbsp;&nbsp;1.&nbsp;&nbsp;From ZWCAD's <B>Express</B> menu, choose <B>Draw</B> -- &gt;<B> Draw Bisector of Angle</B>. (Or, you can input the <B>AngDiv</B> command directly.)</P> <P>&nbsp;&nbsp;&nbsp;2.&nbsp;&nbsp;Choose the sides of the angle and the intersection point of these two sides. </P> <P>This Express function is specially meant for drawing the bisectors of angles. If two lines are parallel with each other, then bisector line is drawn parallel with them.</P> <P>By the way, there are 86 more express tools in ZWCAD's Express menu.They provide many useful functions that are practical and easy to use, such as for drawing arc-aligned text and automatic text numbering. They replace complex steps by one or two simpler ones.</P> </div> <div style='line-height:30px;margin-top:10px;background:#F8F8F8;border:solid 1px #CCCCCC;'> <div style='text-align:left;padding-left:10px;'> Last: <a href='/cad-software-support/cad-tips&tricks/200942821908 PM3441.html' title='Drawing 3D Springs with ZWCAD Professional'>Drawing 3D Springs with ZWCAD Professional</a> </div></DIV> <div style='line-height:30px;margin-top:10px;background:#F8F8F8;border:solid 1px #CCCCCC;'> <div style='text-align:left;padding-left:10px;'> Next: <a href='/cad-software-support/cad-tips&tricks/2009521105248 AM4529.html' title='ZWCAD Tip: X and Y Ordinate Dimension in a Single Step'>ZWCAD Tip: X and Y Ordinate Dimension in a Single Step</a> </div></div> </div> <ul style="height:10px"> <li class="Bottom_1">&nbsp;</li> <li class="Bottom_2" style="width:689px;">&nbsp;</li> <li class="Bottom_3">&nbsp;</li> </ul> </div> <!--End List_1--> </div> <!--End Left--> <!--Right--> <div id="mainRight"> <!--Column--> <div id="rightComm"> <div class="rightTitle"> <div id="LinkTitle"><a href="/cad-software-support.html"><strong>SERVICE & SUPPORT</strong></a></div> </div> <div class="rightList_1"> <a href="/cad-software-support/cad-demo.html">ZWCAD Demo</a> </div> <div class="rightList_1"> <a href="/cad-software-support/cad-documentation.html">Documentation</a> </div> <div class="rightList_1"> <a href="/cad-software-support/license-registration.html">License and Registration</a> </div> <div class="rightList_1"> <a href="/cad-software-support/cad-tips&tricks.html">Technical Tips</a> </div> <div class="rightList_1"> <a href="http://www.zwcad.org/forum/">ZWCAD Forum</a> </div> <div class="rightList_1"> <a href="/cad-software-support/cad-faqs.html">FAQs</a> </div> <div class="rightList_1"> <a href="/SupportRequest.asp">Support Request</a> </div> </div> <!--End Column--> <div id="rightCon"> <div><img src="/images/index_85.jpg" width="224" height="44" /></div> <div style="background:url(images/click.gif);width:224px;height:32px;"> <script language="javascript" src="http://float2006.tq.cn/static_card.js?ltype=100&name=&uin=8214445&utf8=1&onlinepic=http://www.zwcad.org/images/click.gif&offlinepic=http://www.zwcad.org/images/click.gif&where=escape(document.referrer)"> </script> </div> </div> <div id="rightForum"> <div> <a href="http://www.zwcad.org/forum/" target="_blank"> <img src="/images/Company_55.gif" border="0" /> </a> </div> </div> <div class="rightLine_1">&nbsp;</div> <div class="rightConList_1"> <a href="mailto:sales@zwcad.com" style="color:#666666">sales@zwcad.com</a> </div> <div style="background-color:#f2f2f2;line-height:1px;"> <div class="rightLine_2">&nbsp;</div> </div> <div class="rightConList_2"> 86-20-38259726 </div> <div class="rightLine_2">&nbsp;</div> <form name="EmailForm" method="Post" action="EmailAction.asp" target="_blank" onSubmit="return EmailCheck(this)"> <div id="rightMail"> <div class="mailTitle"><a href="/news/newsletter.html" style="color:#000;">ZWCAD Newsletter Subscribe >></a></div> <ul> <li class="mailText"> <input type="text" id="Email" name="Email" align="absbottom" value="Your Email" style="color:#666666;" onfocus="if(this.value=='Your Email'){this.value='';this.style.color='#000000'}" onblur="if(this.value==''){this.value='Your Email';this.style.color='#666666'}" class="mail" /> </li> <li class="mailSubmit"><input type="image" src="/images/mail_10.gif" /></li> </ul> </div> </form> </div> <!--End Right--> </div> <!--End Main--> <!--Footer--> <div id="Bottom"> <div class="bottomLine"></div> <div id="bottomText"> <ul> <li class="bottomCont_1"></li> <li class="bottomCont_2"> <div class="contLeft"> &copy; 2010 ZWCAD Software Co., Ltd.
