4、了绘图效率。同时,系统利用VisualLISP程序来进行设计计算,所有计算操作都在对话框中进行,操作方便快捷,大大缩短了设计周期。而且系统还具有文档文件处理功能,用户在设计中可以把计算文档文件存入系统,以备查看。关键词:液压CAD系统,液压元件图形符号,VisualLISPThePressMachineHydraulicSystemCADAbstract:This system uses the second development systems and pull –down menu and icon menu in AutoCAD, establishes a warehou
5、se of hydraulic parts’ marks, thereby resolved the problem that the designers must do many repetition jobs, and they draw many informal diagrams , increases painting efficiency consumedly. At the same time, the system makes use of the procedure ofVisualLISPto process the design calculation. Al
6、l calculations the operations are proceeding in dialog box, this is convenient and fast, shortened to design the period consumedly. And the system still has function of text file handle, customer can deposit the text file into the compute. The system has the feature such as convenient using and
