The Helix curve function in Catia V5 only allows a helix on an axis or a line.
But there is a trick to create a helix on a spline/curve or polyline.

1. Step 1:

   Create a curve and add a plane on the end of it.
   

   

2. Step 2:

   Create a line on this plane.
   

   

3. Step 3:

   Sweep the line on the curve use the settings shown in the picture.
   Reference surface is "default".
   

   

4. Step 4:

   Create a second sweep - now the reference surface is the previously created sweep.
   Add a law with an end value that fits your desired result.
   Make sure the law type is "Linear".
   

   

5. Step 5:

   Create a boundary with the settings shown in the picture.
   Surface edge is the outer edge of the second sweep.

   

6. Step 6:

   Now your helix is finished and you can sweep a sketch on it to get your desired surface.
