Greetings, I am trying to create a Double Helix.
I thought it would be as easy as using the helix tool >scaling in the y and mirroring…but it looks more like an old phone cord!
If anyone has any suggestions or have already created a DNA helix please post
thanks!
If your single strand is running along the z-axis, you will need to mirror it in both the
X and Y axes at the same time.
I’m afraid I have a head cold am in no real state to say why, except that DNA double helices are anti-parallel; i.e. the two strands are identical chemically (or as good as) but run in opposite directions.
To make the single strand I found it easiest to first make a flat ring out of zsphere and then move each consecuative zsphere out along one axis to which movement has been constrained.
…uh you lost me at “hello” 
Would you mind posting an image?
words confuse me.
Thanks!

You must use a script like Zplace (but a little bug exist yet on the Yrotation for a perfect DNA 
) but this very old script makes the good trick

If you look my gallery I have made some things very more complicated than a double helix
