【摘要】 截面几何性质是结构设计中的重要数据,不同类型的截面形状采用的计算方法不同。着重介绍了一种基于AutoCAD的方法计算平面图形的面积、形心、惯性矩、惯性积等参数,通过与其它方法比较,显现出该方法具有简单、快速、准确和适用于各种平面图形的优点,是一种值得推广的方法。更多还原

【Abstract】 The ichnography geometry quality of the design is important data.The different calculation methods is used for the different types of the ichnography.This paper introduces a method of the ichnography geometry quality based on AutoCAD.This method which is easy,fast,accuratle and suitable for all kinds of plane graphs after comparing with other methods for the calculating of parameter such as area,centroid,inertia,product of inertia is a worthy method.更多还原
