摘要
对采矿CAD系统线框构图技术中的图元属性进行了研究。讨论了图元的非空间属性、空间属性的含义和矿山图元属性的性质、作用和表述方法 ;介绍了 3种可行的矿山图元属性表述方法 :代码法、信息块法和字符串法。实践表明采用字符串法表述矿山图元属性具有高效、编程简单的优点 。
The graphic attributes in line frame techniques of mining CAD are studied.The meanings of the graphic spacial and nonspacial attributes and the properties,functions and describing methods of mine graphic attributes are discussed.Three feasible describing methods of mine graphic attributes,namely,code method,information block method and character string method are presented.The practice has shown that the character string method has the advantages of high efficiency and simple programming,which has been successfully applied in the CAD system of open pit mining scheme.
