    From your model I could not really tell what the desired shape was.
    Looking for Helicoids online, there are many images: https://www.google.com/search?as_st=y&tbm=isch&sa=1&q=helicoid

    I have a feeling this model differs quite a bit from yours, so it could be wrong.
    Do you have an image or sketch of what the final shape should look like?

    I managed to draw a helix on a surface cylinder only by performing a swept material removal (helix) on a volumic body and then I made a surface shift of value 0.
