AutoCAD环境下基于三维模型的二维视图创建方法

对AutoCAD环境下根据三维模型创建二维平面视图,尤其是剖视图的方法进行了分析探讨。方法之一是将三维模型上平行于投影面的表面或表面的轮廓线经复制、编辑、补线等操作,即得到对应于该投影面的视图、剖视图。方法之二是利用截面命令（section）或截面平面命令（sectionplane）创建穿过三维模型的横截面,再经编辑、补线等操作,将该横截面创建成所需的剖视图。

A creating 2d view method according to 3d modelin AutoCAD

The creating view methods,especially creating cutaway view,according to 3D model in AutoCAD are analyzed and discussed.One is to copy,edit,fill line the 3D model surface’s planes or the plane’s contour line that is Parallel to planes section,so get a view or Cutaway view.Another methods is to use ＂section＂command or ＂sectionplane＂command to create a cross section through 3D model.Then edit the cross section into the cutaway view.
