How to draw this irregular form

[Anonymous]

I need to draw this form, but I can´t get the helix option.

Can You help me? 

Step By Step or Suggestions. This format is helical and circular.

Hi! It does not look irregular to me. You need to focus on 1/6 of the model (pattern 6 times later). The path looks like projected to a torus (donuts). It should be doable. Please share your attempt here. Forum experts can help provide further guidance.

Many thanks!

You can get the sweep path via a 3D intersection of torus surface and curve.

Attach the *.ipt file of your attempt if you can't figure it out.

It's been a month since we last heard from you in this thread. Did you model the thing?
