closure screw cap

[tere_106]

I'm almost freaking out. .
I'm modeling a bottle with the screw cap like those of the oxygenated water, here, how do I create the threaded part of the bottle and the relative part of the cap so that it matches?
How do I create them? making the cosmetic thread to the cap then I can not do the corresponding to the bottle, because in the axieme I can not work with the functions of the solids.. .

Tell me if I did something wrong or how would you...

Thank you all!

you need to build the thread three-dimensionally and then do a boolean subtraction.

Sorry, but maybe I didn't understand. .

I think I create a part that will be the bottle and a part that will be the cap and so far everything ok(at least I hope)

then create the axieme that contains cap and bottle.

the threads you have to do in the individual parts and not in the asses.. .

Hello I hope to have been helpful

to make threads I use a helical curve and the sweep command, see many tutorials on you tube...

Hello

Hi, I'm trying after a little stop... Currently as thesis says, I create the propeller and then the sweep extrusion. . select a round profile on the helical path that matches the neck surface of the bottle.
selecting "alline with final faces" does not round me the ends of the sweeps, I would like to avoid that it ends clearly. ..according to you why, what can be wrong?
thanks in advance

I have no idea why you don't flatter your final face as you wish. Perhaps it is not possible since as I think a final face does not exist as the cylindrical part along which the sweep affects the sweep and not only its end.
to re-enter the fillet in the body of the bottle in a naural way you can connect to the end of the helid a short spline, bound tangent or with equitable curvature (try which of the two is better) and that you return gently inside the volume of the bottle.
