helical antenna in CST

hi can anyone tell me how to draw a helix in CST MWS. I can't figure out the points we need to enter.

I haven't design a helix antenna but:
There is an example of "Helix antenna" on CST MSW help. Try to have a look at it.
you can click on "History list" and go through the design step by step.

yeah that's exactly what i am trying to do but when you rotate the profile, i can't get a helix and how can i fix the number of turns. its way easier to make it in HFSS than CST but exporting HFSS model to CST doesn't allow it to be modified
