Help with drawing Radial Stub using HFSS

Please help me in drawing radial stub using HFSS. I have tried arc, polyline etc. But I want to have a radial stub with a thickness, which means it is 3D and not 2D.

I need to know how to draw a 3D radial sub in HFSS. Radial stub is like a slice of pizza.

Please help! It is urgent!
Any reply will be highly appreciated. Many many thanks in advance.

Hi
It's very easy, you should draw your 2D structure then right click on it and from edit select surface and finally select thicken sheet.

Draw the 2D sheet (e.g. with the polyline or whatever), then right-click on it, select Edit -> Sweep -> Along Vector. Select an arbitrary point, press 'z' on the keyboard (to restrict the sweeping onto the z-axis) and click again. Then in the inspection menu correct the z-component of the vector. (You could also use the input boxes on the lower right, but I do not find them too useful).
