Abstract: The problem of establish the parametric library of bolt connecting piece in ACAD was analyzed, and a method of the design of parametric library of bolt connecting piece based on ACAD graph block was put forward. This method decomposed bolt connecting piece assembly drawing into basic graphic block, fit the basic graph block into the bolt connecting piece assembly drawing with the assembly relation. Comparing with the usual method, this method had the advantages of simple manufacture, avoiding writing the complicated parametric drawing program, drawing speed etc.

摘要： 分析了在AutoCAD中建立螺纹连接件符号库存在的问题,提出了一种基于AutoCAD图块的螺栓连接件装配图库设计方法。该方法将螺栓连接件装配图分解成基本图块,利用程序将基本图块直接装配成具有装配关系的参数化螺栓连接件装配图。与通常采用的参数化建库方法相比,该方法具有制作简单、无需编程、成图速度快等特点。
