How to calculate Array Factor in HFSS?

Very Urgent Question:

I have a 3-element dipole phased array in HFSS that I drew without going through Antenna Array Setup. I need HFSS to calculate the Array Factor for this array which is in the shape of a hemisphere. When plotting mag(ArrayFactor) it shows a value of 1 across all theta degrees, which can't be correct.

How do I get HFSS to calculate Array Factor for an Array created manually versus one created using Antenna Array Setup?

Thanks.

could someone please answer this urgent question? Where are all the HFSS folks out there?

Thanks.
