ADS2008U2下的Momentum的问题

记得2005A是可以在3Dview里切个横截面看二维方向图的，
但是在2008U2中怎么也找不到类似功能了，
看帮助里说操作方法为：

• Choose Far Field > Cut 3D Far Field.
• If you want a conical cut, choose Theta Cut. If you want a planar cut, choose Phi Cut.
• Set the angle of the conical cut using the Constant Theta Value scroll bar or set the angle of the planar cut using the Constant Phi Value scroll bar.
• Click Apply to accept the setting. The cross section is added to the Cut Plots list.
• Repeat these steps to define any other cross sections.
• Click Done to dismiss the dialog box.

但是找不到Far Field这个菜单，谁能帮忙解决下这个问题，多谢。
