利用AutoCAD求解任意截面的几何性质

摘要

The geometrical properties of a part section is necessary for uswhen we design a mechanical parts. In tradition way, we have to calculate it by hand, it cost much time and has low precision, now we can work out it easily with AutoCAD, immediately and accurately.%截面几何性质的计算对机械零件的设计及强度校核是必不可少的，而用传统的手工计算方法既费时又费力，还容易出错，本文用绘图软件包AutoCAD非常方便地求解，迅速、准确。
