[第三课]坐标系及建模操作

HFSS中目前有四种坐标系可以设置： [0U!Y/?6lA  
Global CS/Relative CS/Face CS/Object CS   i$gm/ZO  
,7,x9qE"  
HFSS自带帮助文件中可以查到以下用法： "
vQ$RW -  
The global coordinate system is the fixed, default CS for each new project. It cannot be edited or deleted. xZZW*d_b  
H6X]D"Y,  
A relativeCS is user-defined. Its origin and orientation can be set relative to an existing CS. Relative CSs enable you to easily draw objects that are located relative to other objects. If you modify a relative CS, all objects drawn on that CS will be affected and change position accordingly. Z(Fsk4,  
You can define a relative CS to be offset and/or rotated from an existing CS.This feature provides a way for objects made of the same anisotropic materials to have different orientations.   NXb_hF

具体英文含义大家都可以看懂。对相对坐标系进行操作时，该坐标系下所有模型会随坐标系一起变动位置。 [ R1S+i

建立相对坐标系后，同样在（0，0，0）位置新建一圆柱体，如下： 0(\ybppx

在全局坐标系中的圆柱顶面建立面坐标系，并建一小环模型如下：

同理以相对坐标系内的圆柱为对象，建立坐标系，并做键合线模型如下： N+%E=D>
