modeling problem

[Biggmetals]

Good morning to all,
I know it might sound stupid, but I just can't finish this model.
from a pdf3d I am trying to rebuild, without keeping appropriate measures due to this, a component but I don't know how to deal with the modeling of the "head".
I'll put an image for you to understand what I'm talking about.what blocks me is that fitting or otherwise semicircularity that follows the whole edge.My model is what I attach to you images:
It's like having the writer's block... o
It would only be enough for me to understand how to deal with it because I swear that it's all morning that I can't get over it and it gives me a nuisance that you don't imagine, because I know it's my "mancancy" in coming alone. .

Thank you in advance!

Maybe because you started from a whole body from revolution.
You could do the part under a revolution and then over do an extruded octagon and then go on with another extrusion that rake.

exactly, allego screen of the starting sketch but I'm sorry I can't figure out what you mean by "extrusion shaking"
(it is not totally defined because until I solve with the cock that I put the measures )

You could do for revolution until under that chord that gives you bored then on you do an extruded octagon and make the fittings on the sides then on you do another extrusion with disform so you do the facets.

OK, I understand how you mean, but I can't give the right value to the rays of the fittings because of that straight thickness; due to obviously the largest hexagon of the revolutionary part below.

if you place the file you can give an eye. another way is to do the part below for revolution, 1/8 of the part above with the surfaces then repetition, lean to the face flat sup and make the "cat" for revolution and you should conclude

I may have understood but you should attach me model 3d

 

[Biggmetals]

attached model. specific that is a file v.2016

Eh saperle usare le superzare, asses...

Why don't you take the diameter of the hat to the edge alive and then make the radius?
Or do you ray directly into the sketch?
that then the original is a repetition of a slice (you see the upper edge straight) and not a cut of a revolution like your (you see the upper edge concave)

so it should go. But today I have little time so I went very fast.
you could do it better with less functions or rebuilding the model.

You better make an octagon and extrude it with the deform. And then you're making him the radius

 

[Biggmetals]

thank you all for the answers! at the end of the modeling place the result

Thank you very much!

the final result is equal to my model and is blocked as in my post #5 but thank you anyway!

Okay. mine was an example, if you varied the fictions you could have run as you wanted.
However, as he said, Mass is fine.

I apologize then, it is that I have 2016 and yours I just imported it, so I couldn't look at the functions used
Can you attach me a function screen?

I managed to finish the model in the day, thanks to everyone for the help!
