CAD/CAM建模构型方法总结与实践

Summary and Practice of CAD/CAM Modeling Method

从二维草图绘制和三维造型两方面建立了草图、建模的思维体系,提出了设计基准先行原则、草图绘制与修剪、标注尺寸与图形检查、操作技巧和快捷键应用4种二维草图绘制方法;归纳了叠加组合法、整体局部法、综合构型法3种三维建模构型方法。通过近5年的教学培训实践,以上方法有效地提高学生的绘图建模能力,在竞赛培训项目获得佳绩。

The thinking system of sketch and modeling was established from two aspects of two-dimensional sketch drawing and three-dimensional modeling.Four methods of two-dimensional sketch drawing were put forward,including the principle of design basis first,sketch drawing and trimming,dimensioning and graphic checking,operation skills and shortcut key application.Three methods of three-dimensional modeling were summarized,including superposition combination method,whole local method and comprehensive configuration method.Through nearly five years of teaching and training practice,the above methods can effectively improve students′drawing and modeling ability,and achieve good results in the competition training project.
