ＡＤＳ是一种Ｃ语言编写的用于开发ＡｕｔｏＣＡＤ的应用程序系统，ＶＢ是Ｗｉｎｄｏｗｓ环境的开发工具，提供了ＶＢＡＤＳ函数。利用ＶＢＡＤＳ程序向ＡｕｔｏＣＡＤ发送命令可生成三维网面图形。阐述了应用ＶＢＡＤＳ程序建立三维图形的基本方法和程序，介绍了这种方法在三牙轮钻头应力计算和分析中的应用，并给出应用此方法绘制的三牙轮钻头滑动轴承油膜压力三维图形，以及滚动轴承直线型滚动体和直线与圆弧相交型滚动体接触应力三维图形。这种方法也可用于其它机械零件的有限元分析。
ADS is a C language for the development of AutoCAD application system, VB is a Windows environment development tools, VBADS functions. Use VBADS program to send commands to AutoCAD can generate three-dimensional mesh graphics. The basic methods and procedures of establishing 3D graphics using VBADS program are described. The application of this method in the calculation and analysis of the stress of the tricone bit is introduced. The three-dimensional graphics of the oil film pressure of the tricone bit bearing , As well as rolling bearing linear roller and linear and circular arc contact roller rolling contact stress three-dimensional graphics. This method can also be used for the finite element analysis of other mechanical parts.
