1. Step 1:

   1. Create the sketch
   2. Select Front plane
   

   

2. Step 2:

   1. Create the Center line. This is will be the axis of the helix.
   2. Snap the line to vertical reference.
   

   

3. Step 3:

   1. Create the line.
   2. Edit the hight of the line to 200 mm. This will be the height of the helix. 100 mm - the radius of the helix.
   3. Finish the sketch.
   

   

4. Step 4:

   1. Activate Helical Sweep tool
   

   

5. Step 5:

   1. Select the sketch as a profile.
   2. Start to edit the crossection.
   

   

6. Step 6:

   1. Create the rectangle.
   2. Snap to the reference of the profile.
   3. Create the dimension = 0. Not needed to snap to horizontal reference.
   

   

7. Step 7:

   1.Open Tools -> Switch Symbols
   2. Remember the name of the dimension - sd7
   

   

8. Step 8:

   1. Open relations window.
   2. Past this text

   /* The height of the wave
   amp=10

   /* The mumber of the waves
   col = 4.5

   k= 1/(d1/d2)
   sd7= amp * sin( trajpar *360/k * col)

   3. Close the window and finish the Sketch and Helical Sweep
   

   

9. Step 9:

   Result!
