hfss draw trapezoid

hi,
im trying to simulate an horn antenna which is fed by a rectangular waveguide in HFSS. i dont know how to specify the flaring angle for the waveguide end to form horn shape. i tried with sweep through vector.but couldnt get results. give me some suggestions regarding it..

dear mubassira;
what you wanted is done easily in 3 step:

you can draw all the faces by polyline menu one by one
(for example you should draw 2 rectangle 4 trapezoidal faces for a primidal horn)
and

convert the faces to surfaces by coversurface
and then

unit them as a solid.

I can explain more if you want.
