How to build a sqaure in 2D axis symmetric geometery

Hello

I have got stuck in to very simple problem, I have a built a 2D axis symmetric circular plate to model my inductor and in addition I want to add a metal square late. I have to use to 2D axis symmetric to get a circular coil but when I try to use rectangle in axis symmetric it becomes circle. Can't I make a normal 2D in 2D axis symmetric or vice versa
I have attached the 3D model of what I want

Regards
