摘要
特殊平面图形的面积、形心、惯性矩、惯性积等参数采用公式计算繁琐、费时。研究给出了基于AutoCAD的计算截面几何性质的一种方法。该方法使用AutoCAD绘图命令绘制出图形,采用面域命令将其制作成面域,对复杂图形还必须再进行差集和并集运算,然后根据计算需要用UCS工具条上的工具移动坐标原点,最后使用查询面域工具可以快速查询出该平面图形的几何性质。这种方法使得计算变得简单易行,且数据易于保存、查取和调用。
This paper gives a speedy method of the ichnography geometry quality based on AutoCAD.This method can be easily implemented for the Calculating of parameter such as area,centroid,inertia,product of inertia by its graphics and inquiry functions.This method uses AutoCAD drawing commands to draw a graph,the special parameter is made into the region by using the region,union and subtract commands,and then the ichnography geometry quality are checked out by query tool after moving with the origin of coordinates.
