摘　　要：基于AutoCAD2002由三维模型生成二维投影,是计算机辅助设计和绘图的一种有效方法,通过实例介绍一种方法可以实现从三维到二维的转换。此方法利用图纸空间的浮动视口把三维模型对不同方向用Solprof命令生成三视图及轴测图的轮廓图,把生成的轮廓图剪切于一个新文档中进行编辑,进而方便地得到三维模型实体的三视图、剖视图及轴测图等二维投影。用这种方法绘图,所得的二维投影符合真正的投影关系,因此不易产生投影错误,这为生产实践和教学带来方便。The method of transforming 3D model into 2D views based on AutoCAD2002 is effective on the computer aided design and computer aided drawing. The paper presents the method to realize the transforming by means of real examples. In the method, the 3D model is projected onto different projective skeleton map for making the projective outlines by using the command'Solprof', these profiles are cut and pasted into a new drawing file to edit. The views, section views and axonometric projection of 3D model could be abstained. By the method, the 2D views are accorded with the projection of 3D model, so there could be fewer errors in views. It would bring convenience into engineering using and teaching.
