hope this will help.

1. Step 1:

   create a solid profile as shown.
   

   

2. Step 2:

   make a vertical line (greater than radius of curved profile) on the face as shown.
   

   

3. Step 3:

   on same face, but in another sketch make a circle of radius same as length of line.
   

   

4. Step 4:

   use this circle to make helix of required height and pitch.
   

   

5. Step 5:

   now draw a line equal to height of helix as shown.
   

   

6. Step 6:

   now make surface sweep...vertical line as profile...horizontal line as path... and helix as guide curve.
   

   

7. Step 7:

   now in 3D sketch module, choose intersection curve (in Tools-->sketch tools-->).
   Choose complete solid profile and surface sweep to make a intersection curve.
   

   

8. Step 8:

   this will make a curve profile on the surface of solid profile. hide sweep surface and it will look like as shown.
   

   

9. Step 9:

   use this profile as path for sweep cut thread profile.
