Drawing a helix screw in fusion360

Just wondering if anyone could help me with learning how to draw a helix screw with a changing pitch in fusion. I know how to import a csv file but as for the maths to calculate its straight over my head.

many thanks

I cant help you directly, but i would strongly recommend checking lars Christensens youtube channel out:
if you don’t find what you need i would write an e-mail to him, he usually replies within a day or so.
hope it helps 🙂
