摘要
通过对三维实体建模实例的分析,讨论了在 AutoCAD 系统中进行三维建模的方法,分析了用户坐标系(User Coordinate System,UCS)上变换和布尔运算在三维建模中的应用及重要性,展示了利用 UCS 变换和布尔运算创建三维图形的方法和技巧。强调应养成良好的建模思维习惯,灵活应用各种绘图和三维编辑命令。
By the analyses of the modeling of three-dimensional bodies, the method for threedimensional modeling in the AutoCAD system is discussed. The application of UCS transformation and Boolean operation on the three-dimensional modeling and their importance are analyzed. The methods and skills of creating three-dimensional graphics by the use of UCS transformation and Boolean operation are illustrated. It is emphasized that a good habit of modeling thinking is important to flexibly use a variety of graphics and three-dimensional editing commands.
