In case of helical curve, If a taper spring is about to draw and top dia, bottom dia and height is given so how can I create helix based on this?

Hi Solidworks Users,

I am about to create a taper spring where top dia, bottom dia and spring height is given so how can I create taper helical curve based on this? Solidworks always ask 'angle' to create taper helix. But there is no angle data is given. How can I calculate angle for helical spring? No taper ratio is given too?

With  regards,

Soumya
