Help in designing Spherical Helix antenna

Hello.

I have a final project which invovles desiging 4 arms spherical helix antenna in Hfss.
I asked around a little, but no one has any idea how to get to it.
One of my ideas was to draw the design in matlab and then build the model in Hfss using the coordinates.
Anyone has any idea how to convert a set of (x,y,z) coordinates from matlab into a countour in HFSS?
Or any other idea on how to design such an antenna?

Thanks.

In HFSS, draw the cross section of the helix (where it will be located at the bottom of the helix). Select your cross section surface and then from the Draw menu, choose Helix. Then you set the properties of the helix and choose the center point of the helix.
