Double Helix

Does anyone know how to make a double helix on inventor, i am sort of new at this please help me.

i dont have it open rightnow but i think you can draw an axis line on a sketch with 2 circles opposite eachother with the line as an axis.
then finish sketch and then “coil” i beleive it was called… correct me if im wrong. and then you can playwith that. luck!

It worked thanks
