摘　　要：为了实现多管相交时切割线的参数化设计,采用几何法和三维坐标变换的思想,对每一根管表面展开的给出了与其他管相交的展开及相贯线算法的参数公式和开发步骤,开发出了多通管件立体图及圆柱表面展开图的绘图命令;该命令由基于参数化绘图方法的Lisp程序和基本尺寸参数输入实现,同时列出了需要输入的基本尺寸参数。In order to realize the parametric design of the cutting line when multiple tubes intersect,the parameter formula and development steps of the expansion and intersection line algorithm that intersect with other tubes are given on the surface of each tube,and three views of multi-pass pipe fittings are developed The drawing command of the expanded drawing of the sheet metal on the cylindrical surface;this command is realized by the Lisp program based on the parametric drawing method and the basic size parameter input dialog box.At the same time,the input conditions and parameters of the basic size parameter are listed.
