【摘要】 提出并实现了一种新的参数化标准件文件的生成算法。利用标注信息,转化图形为点集;通过点之间的关系,描述图形的几何拓扑约束。该算法自动生成基于中间语言的参数化标准件文件,提高了参数化标准件的生成效率,实现了建库过程的可视化和便捷化。更多还原

【Abstract】 A new algorithm building parametric standard part file is presented,which using information of marks,translates an engineering drawing into a serial of points,and making use of the relation between points,describes the geometrical and topological constraint of drawing.Then a parametric standard part file that is described in a special language will be automatically built.The efficiency of building parametric standard part is improved,and the briefness and visualization of building library process is realized .更多还原
