Hi, is anyone aware of a library which allows me to make a progressive pitch helix if I input radius, starting angle, ending angle and number of turns?

Guest4: I don't remember seeing that, but then it's not something I have searched for specifically

I suppose the candidate to look for would be BOSL2, it does have some powerful general tools

progressive pitch helix...
22:34

so just a bent helix?

cylinder().union(cylinder).twist(degs).bend(degs)

sdfs are amazing

bent helix? picture for example the propeller from a ship, blades are at an angle. Similar principle, only applied to an impeller, the difficulty comes because I want the beginning of the impeller to have a pitch of 14.5 degrees and increase progressively ending at 18.5 degrees
