选煤厂计算机辅助设计中参数化绘图功能的实现

摘要

In accordance with the question of big workload of drawing and difficult found of gallery of faclity in CAD of coal preparation plant, this paper analyses the characteristics of the shape sameness and size unlikeness. Adoptting the parametrization drawing method, the drawing programmes of equipment using parameter are developed. The work is beneficial for improving the efficiency of drawing, reducing the workload of building warehouse, saving the EMS memoery.%就选煤厂计算机辅助设计中存在的绘图工作量大、设备图库建立困难的问题，分析了某些形状相同、大小不同的设备的特点。采用参数化绘图的方法，开发了设备参数化绘图程序。提高了绘图效率，减少了建库工作量，节省了内存。
