The helix in nano-scale

Hi, I meet a problem when I was drawing a 3D helix in nano-scale.

700 nm, 650 nm, 600 nm are chosen to be the variable pitch of the helix (3 revolutions), the radius is 1325 nm.

 

But, if I choose the Units of Length to 'nanometers', the pitch value must greater than 1E5 nm and less than 2E11 nm which the Solidworks displays, that is not suitable to my case.

If I choose the Unites of Length to 'microns' and enlarge the whole parameters of the helix (700um, 650um, 600um of the pithches I mean), I can draw it. But when I scale down it to nano-scale, the lines are not regular and can not be used.

 

Anybody know how to draw it appropriately?

 

Thanks,
