摘要
利用计算机进行二维绘图在我国已经得到普及,但直接进行三维设计还比较少.为了便于大家学习和掌握三维建模,介绍了三维模型的表示方法以及AutoCAD的三维建模功能.对操作过程中出现的用户坐标系(UCS)图标的用途与含义进行了归纳总结,并简单介绍了UCS的定义、管理及用户坐标的输入方法;最后,结合实例介绍了UCS在实体建模中的具体应用.
It is already popular in China to draft 2D drawing with computer,but it is less to perform design in 3D directly. In order to help users to study and use 3D modeling,this paper introduced its representations in computer and functions in AutoCAD, the usages and significations of user coordinate system icon appeared in operation were summarized. The definition, management of user coordinate system and the ways to input user coordinates were introduced. At last,an example to use user coordinate system in solid modeling was given.
