工程图图廓自动绘制程序的设计与实现

Design and Implementation of Automatic Drawing Program for Engineering Drawings and Profiles

图廓信息承载着地形图最基本、最重要的信息。工程测量项目成果通常需要提供图幅接合表、控制点展点图、控制网略图、测区示意图、水准路线图等成果图件。为准确表达这些图件的相关信息,通常需要绘制测绘单位或者测绘机关、图名、比例尺、内外图廓、公里网及其注记等信息。为满足《图式》关于图廓的相关要求,人工绘制图廓不仅烦琐并且字体、线型不规范,如果需要重新修改或调整工作量极大。笔者基于AutoCAD二次开发了工程图件图廓绘制程序,实现了参数化和标准化的图廓绘制,极大地提高了绘制效率和正确性。

The map border information carries the most basic and important information of topographic maps.The results of project survey usually provide index diagram,control points,control plot area network sketch map,diagram,level line and other engineering drawings.To convey the information related to these maps,usually need to draw their mapping units or mapping agencies,map name,scale,inside and outside the border,the network and its notes and other information.In order to satisfy the requirements of Cartographic symbols for national fundamental scale maps,the manual drawing is not only tedious,but also the font and linetype are not standard.If it needs to be modified,the workload of adjustment is great.Based on AutoCAD,the author has eveloped the program of the drawing of the engineering map,and realized the parametric and standardized drawing of the contour,which greatly improved the drawing efficiency.
