ARX在换热设备管板布管CAD系统中的应用

在换热设备设计中 ,采用AutoCAD二次开发技术 ,在VisualC 6 .0和ObjectARX 2 0 0 0的环境下 ,开发了管板布管CAD系统。在给定基本参数如换热器公称直径DN ,换热管直径dh,管程数N ,拉杆数Ni 等条件下 ,自动计算换热管根数和管孔中心坐标 ,并精确绘制出CAD布管图。该系统准确、方便、省时 ,界面友好 ,实现了从数据到图纸的计算机参数化绘图。

Application of ARX in Heat Exchanger''''s Tubes-CAD System

In design of heat exchangers,the heat exchanger's tubes CAD system is developed by adopting Auto CAD secondary developing technology with Visual C 6.0 and object ARX2000.When some basic datum(diameter of heat exchanger DN,diameter of tube d h, number of tube side N and number of rodes N i etc.) are given, the system can not only calculate automatically the tubes number and coordination of tubes center, but also can draw precisely the CAD tube distribution drawing.This system is precise,convenient and realizes parametered drawings from data to drawing. Key words:secondary development of AutoCAD ; object ARX2000 ; heat exchanger ; parameterized drawingering on organic food industry are discussed. As a result, there is an urgent need for the organic movement to quickly co-ordinate activities to keep organic food permanently free of genetically engineering organisms. Organic farming has to face the compelling challenges to set up a completely separate alternative food market.;
