本文介绍一份用微型计算机与绘图机计算、显示和绘制公路透视图的程序。利用该程序可连续显示或打印计算路段线全线线形透视图,也可根据需要绘制单幅或多幅透视图,直接作为设计文件。程序使用方便,只要根据计算机屏幕的提示进行操作即可。 This article presents a program that uses microcomputers and plotters to calculate, display, and draw road perspectives. The program can be used to continuously display or print the line of the entire line of linear perspective, but also can draw single or multiple perspectives as needed, directly as a design file. The program is easy to use, as long as the computer screen prompts to operate.
