摘要
本文提供一个简洁通用的程序,对于由直线、圆弧及波浪线组成的任何图形均可实现自动绘制剖面线。本文还重点介绍了如何用二次B样条曲线代替波浪线,解决局部剖视图中剖面线的画法。
This article introduces a succinct and universal program, which draws section lines automatically for any figure composed of straight lines, curves and wavy lines in stead of the tedious methods of drawing part by part, This article also centers on how to replace wavy lines with B spline curves twice so as to solve the problem of drawing sectional lines in local sections.
