摘要
将带有螺纹的实体分解成螺纹和螺纹载体 (圆柱体 ) ,螺纹的表面由螺旋面或螺旋面和螺旋形圆柱面组成 ,用三维表面取代三维实体构造螺纹 ,利用AutoLISP程序绘制螺旋面或螺旋形圆柱面的导线 。
Break up the body with screw thread into screw thread and boby which carry screw thread.The surface of screw thread are made up helical or helical and helical surface of cylinder.Construct screw thread with three dimensional surfaces instead of three dimensional entity.Draw up cylindrical spirals which are lead of helical surface by means of AutoLISP program and then create helical surfaces and helical cylinder surface by command“rulesurf”.
