【摘要】 主要介绍了绘制三维螺旋圆柱、圆锥弹簧的多种方法,并采用AutoLISP语言编制程序进行二次开发,为AutoCAD新增三维螺旋圆柱、圆锥弹簧命令,使得在机械产品三维设计CAD时,绘制三维弹簧更为方便,提高三维设计的绘图工作效率。更多还原

【Abstract】 Modeling methods of 3D cylinder or taper spring are discussed, one of which uses AutoLISP language to develop some new functions in AutoCAD and add the commands of drawing 3D cylinder or taper spring model in AutoCAD. This method is very useful and convenient in the process of CAD in 3D of mechanical productions. The efficiency of designing and plotting will be greatly improved.更多还原
