Far field polar plots in cst

How do i create a polar plot of an antennas farfield as a function of spherical angle phi? I can only generate a 3D plot and I'm basically trying to get a cutplane of this result.

Hi,
in the set of farfield (plot properties) you can set polar plot.

hii
its very easy just left click on the 3D plot and then go plot properties and select polar plot option then u get ur desired plot..
