Help! broken down thread in PET bottle cap

Help! broken down thread in PET bottle cap

Help! broken down thread in PET bottle cap

(OP)
in some bottlecaps you see a thread broken down in smaller "lanes". What is the best way to construct such a thing? I have tried to create a small secment of helix and then use 'curve driven pattern' on reference 3D spline (from a helix)  to create a continuous thread pattern. In the property manager, I selected tangent to curve to create continuous pattern on the spline. However, when it comes to select 'normal surface' it wouldnt let me!
what have I done wrong? is there another way to model such a thread?
Many Thanks

Model a continuous helical thread.  Then extrude-cut to create the gaps.

Thanks to Handleman! Honestly, I made it too complicated myself. your way is simple and easy to accomplish!

RE: Help! broken down thread in PET bottle cap

Could you post a screen shot of the way you have modeled  it ??
I am always interested in different ways people model simple things like this .
  I try to do the same thing in a smaller feature tree ,I take it as a challengewinky smile I'll post a screeny of the way i did it .It could be an education for both of us.
  Thanks
