thread "true"

[scalva]

Hello, everyone.
Is it possible to make a thread like the one I attach? i.e. in practice it has to end as a thread made with tool on the lathe and when the tool ends up working out from time to time.
I have now done it with an artifact, that is, the first piece is made with a propeller and the last half round made with a conical propeller but it is not real.

You think you can make it?

Thank you.

but let's attach 'the files that people should not escape to hypothesize how the details were made or should remake them of zero with perhaps other techniques.
exists from a certain version the function that performs the real thread beyond the cosmetic one

I tried with the thread but I can't do what I want
I attach the file
If I can.... .

I don't understand the problem. If I enter the piece or go out of the piece with the tool I make a conical propeller. then the rest of the thread will be cylindrical.

No problem
I just wanted to figure out if there is a x method to model the thread that I did with 2 functions with only one made by the software
Actually when you work on the piece by force it is so.
