摘要
在工程制图中经常采用一些近似画法绘制椭圆,本文通过对菱形法画椭圆所产生的轮廓误差的量化分析,提出了一种修正方法,可使绘出的椭圆愈加精确,同时,还利用计算机技术得到了一些有价值的曲线图,为绘图人员用菱形法精确绘制椭圆提供了理论依据和技术指导.
This paper analyses the errors of the approximate ellipse constructed with the rhombusmethods, on the basis of it, An improvement method is put forward and a few diagrams ofcurves are obtained on the PC. therefore, It is very important and helpful for us to exactlyconstructed an approximate ellipse with the rhombus method.
