基于AutoCAD和VBA的地形图自动分幅程序设计与实现

Design and Realization of Automatic Framing Program for Topographic Map Based on AutoCAD and VBA

针对当前工程建设大比例尺地形图及土地勘测定界图分幅中存在的图形破碎、自动化程度低等问题,该文利用将地形图分幅至布局的思路,采用VBA作为主要开发工具对AutoCAD进行二次开发,实现了标准图幅(50cm×50cm)以及非标准图幅(A1、A2、A3)的一键自动分幅,提高了分幅效率,同时保证了分幅的准确性,具有较好的推广价值。

Aiming at the problem of broken graphics and low automation in the division of largescale topographic map and land survey and demarcation map in current engineering construction,the idea of dividing the topographic map into the layout is used in the paper,the VBA is used as the main development tool for AutoCAD secondary development.The one key automatic framing of standard map frames(50cm×50cm)and non-standard map frames(A1,A2,and A3)is realized,which improves the framing efficiency and ensures the accuracy of the framing.It has good popularization value.
