拉伸法快速绘制轴测图的研究

The study of axonometric drawing with stretching method

根据轴测投影的基本定理和正投影图,在AutoCAD中不用坐标变换,也不用UCS系统及三维造型技术,仅用拉伸、复制、平移、修剪等常用的绘图技术,即可快速绘制出各种理想的轴测图,免除了不停变换坐标系统和逐个输入各点坐标的烦恼.此方法独特,方便快捷,易学易用,充分发挥了AutoCAD的常用绘图和编辑工具的优越性.

On the basis of fundamental theorem on axial projection and ortho projection chat, there is no need to change coordinates in AutoCAD. Neither UCS system nor three dimentional sculpt technique will be adopted. Only common drawing techniques such as streching, copying, moving and trimming make it possible to draw various types of ideal axial maps, without constantly changing coordinate systems and inpecting coordinates one after another. This kind of method is special, convenient and easy to grasp, which takes the advantage of AutoCAD′s common drawing and editing tools.
