摘要
本文对采矿CAD系统中基本图元集的构造及其表述方法进行了研究。提出了一个 7元素采矿CAD基本图元集构造方案 ;讨论了曲线图元和尺寸标注图元的表述方法 ,提出用“多边形图元”代替“曲线图元”。该图元集构造方案对基于线框构图技术的采矿CAD软件开发有一定的指导意义。
Based on study of the structure of basic output primitives for mining industrys CAD system and the configuration method of these primitives,a scheme to build a set of basic primitives for CAD system used in mining industry with 7 elements is introduced.The configuration method of curve primitives and size indicating primitives and the idea of replacing the curve primitives by polygon primitives are studied.The new set of output primitives has great directive meaning for further development of CAD system used in mining industry.
