Would recommend just creating a circle, off of that create a helix/spiral, then sweep the profile down. It’s really not that hard…
Now the reason why people recommend not creating the threads is that the only reason for actually having them is if you plan on doing an FEA anaylisis and need the collision detection to happen. Otherwise it’s not needed. You also have the SW toolbox, GrabCad, 3D Content central, and mcmaster carr’s library to just download the model and go. Or if you are really pressed then download the model and roll the history back to see how it was made.
