HFSS近区场设置的问题

我设置近区场line形式的时候报错，there were no exsting lines for creation of this setup ,please use the geometry editor to creat lines before creating near field line setup.这个creat lines具体应该怎么画?哪位高手知道的请教一下，谢谢！很急

是指近区引入场么（near field wave）?那应该是link吧

是near field，在hfss，radiation，insert nearfield setup，line里面加的，不是楼上说的那个
