How to project a Helix in a curved cylinder

Now I understand what you meant by 'curved cylinder'. I didn't pick up on that. Here's a brief, simplified demonstration:

1. Step 1:

   Once you've established the form of the bottle, the first step is to create a helix concentric to the bottle.
   

   

2. Step 2:

   You will use this helix as the path of a spiral 'swept surface' feature.
   

   

3. Step 3:

   Then you create a 3d sketch and select the bottle surface and the spiral surface and use the 'intersection curve' tool to create the helical path that follows the bottle curvature.

   

4. Step 4:

   Finally, use this 3d sketch as the path in the 'swept cut' feature that forms your helical grip.

   

5. Step 5:

   I've attached the model used in this tutorial in case it can be of help. I'm sure your bottle and grip will be much more beautiful than mine, this was just a quick demonstration of the features you'll need.
