how to operate sweep function in hfss?

Hi Aparna

There are couple of ways of doing it.try this

Select your 2-D polyline -->draw---->sweep---around vector or around line.

or pick a 2d surface to be extruded, Modeler---> surface---->movefaces---> and then appropriate option

Let me know if you need further help
