根据装配图拆画零件图

<p>根据装配图拆画零件图<br/>打开文件，如图所示，由此装配图拆画零件图。这个练习的目的是使读者掌握用AutoCAD拆画零件图的方法和作图技巧。<br/><img id="img_0.7387662840786693" height="272" alt="" src="http://www.ttketang.com/home/attachment/200909/2/113_1251857576rVtV.jpg" width="380"/><br/>图10-1&nbsp; &nbsp;由装配图拆画零件图<br/>1.&nbsp; &nbsp; &nbsp; &nbsp; 创建新图形文件，文件名为“筒体.dwg”。<br/>2.&nbsp; &nbsp; &nbsp; &nbsp; 切换到文件“10-1.dwg”，在图形窗口中单击右键，弹出光标菜单，如图10-2所示，选择“带基点复制”选项，AutoCAD提示：<br/>指定基点:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; //指定复制的基点A<br/>选择对象:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; //选择筒体零件<br/><img id="img_0.39883182117306204" height="277" alt="" src="http://www.ttketang.com/home/attachment/200909/2/113_1251857579jutF.jpg" width="368"/>
