基于UCS下的零件实体设计

The Design of Material Object Parts Based on UCS

应用AutoCAD创建复杂的三维模型,只在1个固定的坐标系中创建是非常不便的。通过利用建立不同的用户坐标系,可以使处理图形的特定部分变得更加容易,能方便、快捷、准确的创建形状各异的零件实体。根据机械零件的具体结构、形状,正确理解和灵活变换用户坐标系是三维建模的重要技巧。

It＇s not convenient to set up the complicated 3 - dimensional model in a fixed coordinate by using AutoCAD. Through setting up different user＇s coordinate system, the processing of specific parts of drawings will become easier. In addition, the setup of various spare parts will be convenient, fast and accurate. Based on the specific structure and shape of mechanic spare parts, accurate understanding and flexible shift of user＇s coordinate system is an important skill of 3- dimensional model.
