How to model NPT screws?

[KPeter]

Hi, please check this thread for making tapered threads

Tapered thread

I need to draw up and print a tapered thread and I see there were a couple of threads started several years ago but none seemed to go anywhere. One was requesting advice to do exactly what I need to draw up but unfortunately the advice given was so short and cryptic and doesn’t make sense and isn’t helpful. Anyone have any advice on drawing up a thread on a truncated tapered cone? thanks
