Slice view in HFSS

I simulated wave propagation in a rectangular waveguide in HFSS. For postprocessing, I would like to know how to get view of a contour (or vector) plot on a chosen plane in the waveguide. I just want to see the vector plot on a plane inside the waveguide and not inside the whole waveguide. Thanks.

I was able to figure this out. I drew a plane in the model and then plotted the contour. This plots the contour only in the plane that I drew.
