利用AUTOCAD软件求取图形面积

FIGURE OF MAP AREA BY USE OF THE SOFTWARE AUTOCAD

利用计算机辅助设计与绘图软件ＡＵＴＯＣＡＤ在计算机及其外设数字化仪上求取规则或不规则形状图形的面积和周长，在速度、精度、操作简单程度等许多方面，不但优于传统的各种求积仪，也比一些专门为计算机及其外设数字化仪编制的求积软件优越，它既可专门求取某一图形的面积和周长，亦可求取利用ＡＵＴＯＣＡＤ软件所绘图形文件中任一图形的面积和周长。如何充分利用该软件求取图形面积和周长的方法作了较全面的介绍。

Making use of the computer aided design and drawing software AUTOCAD to figure the area and perimeter of regular or irregular maps on the computer and the peripheral digitizer is not only superior to the traditional planimeter in speed,accuracy and simplification in operation,but also superior to some planimetric softwares specially designed for computer and its peripheral digitizer.AUTOCAD may either figure the area and perimeter of a given shaped map or figure the area and perimeter of whatever shaped maps in the map documents drawn with the software AUTOCAD.However,there was no detail introduction to this method in former theses that dealt with software AUTOCAD.This thesis does give a full explanation how to make full use of AUTOCAD to figure the area and perimeter of maps.
