摘要
本文阐述了轨道衡辅助设计及绘图系统 GDHCADD 的内容、功能及其应用.该系统采用图块拼装方式完成轨道衡工程的施工设计或竣工图,适用于轨道衡为 GGG-22F 及 LT-03两种型号的多种不同组合情况,并采用绘图作业管理程序 GJM 和 WJMF,以实现系统的组织.
Describes the emphasis on its system design approach,function,as well as application for designing and drafting railway scales.The method of drawing blocks assembly is adopted to accomplish the railway scale construction design or completed blue-prints.The types of railway scale adapted to the system are GGG-22F and LF-03, together with a variety of their combinations.The process is organized and implemented by means of drawing job management programs GJM and WJMF.
