make sheet metal pipe and then stretch it

I have to make a dip tube to be sent to the laser so I need to work it in sheet metal and then stretch it.
I have already read suggestions like the following about how to do it but I can't.

"with extruded cut parts as plane from one of the two faces "head", sketches a closed silhouette (I make a sort of isoscele trapeze with the radial tilted sides and the bases circle arches on the outer and inner circonf of the tube. as a term condition from the blind and the length of the tube (or more convenient passing, or until the next). sending and cutting is done.
now you have to turn that pipe cut into a sheet metal;
insert > sheet > folds in the first panel at high selections one of the two longitudinal edges (split) that have resulted from the cutting before, sending and you have your sheet "rolled" (check the featur manager as it has changed and what has been added).
now always to insert > sheet > extend touches still one of the edges of the cut, the cylindrical face, sending and you have your tube "distinct on the top".
It's very simple and swx allows you to do this and other with the plates. "

tells me errors in the reconstruction, select one or more folds

So what?
You think that on the basis of a "can't tell me mistakes..." we can understand what your problem or your model is?
When you wrote, did you try to identify who reads you? I tell you, you didn't. do it and you will see that you will add to the new post all the elements that are needed because anyone else who is not you understand what you are doing.

I thought that by inserting the suggestion of a discussion of the forum I had already been clear but obviously I was wrong.
then I have to make a tube and make it in sheet metal for displacement and then obtain it lying and create the dxf to be sent to laser cutting.
not knowing how to do, because the sheet functions I never used them, I found in the forum the following suggestion:

"If you have the 3d of the "closed" tube, you must create a longitudinal cut on the generator (but you still haven't used solidworks?). with extruded cut parts as plane from one of the two faces "head", sketches a closed silhouette (I make a kind of isoscele trapeze with the radial tilted sides and the bases arcs of circle on the outer and inner circonf of the tube. as a term condition from the blind and the length of the tube (or more convenient passing, or until the next). sending and cutting is done.
now you have to turn that pipe cut into a sheet metal;
insert > sheet > folds in the first panel at high selections one of the two longitudinal edges (split) that have resulted from the cutting before, sending and you have your sheet "rolled" (check the featur manager as it has changed and what has been added).
now always to insert > sheet > extend touches still one of the edges of the cut, the cylindrical face, sending and you have your tube "distinct on the top".
It's very simple and swx allows you to do this and other with the plates."I followed step by step this suggestion though when I insert > sheet > folds sw gives me the following error: "This bending processing function failed due to the negative outcome of sheet opening function." then opens a window with writing: "No bending was found."
at this point signals the error and I can not even extend the sheet.
How can I do that?

You were wrong.
Unfortunately you continue to be wrong again.
even in this post indicated a series of error messages that do not serve anything, or better serve to tell you that for the software "no bending was found", but you already know that.
see if you give us directions and useful material to understand where you are wrong and can help you.

the cutting lines opening the calandrate converge at the center of the cylinder?

it doesn't seem difficult to understand marcof since I'm following step-by-step the suggestion I posted so it seems to me obvious that:
1) I have to make a sheet metal tube and then stretch it to create the dxf for laser cutting
2) I don't know how to do so I followed the post suggestion
3) I started from a tube in 3d
4) with insert > sheet > folds I had to turn it into sheet metal and then stretch it but it gives me error
5) I ask for help

It's not that hard to understand what I'm doing.

but we start from zero
I want to create a sheet metal tube and then stretch it and create the dxf for laser cutting tips?
 
and anyway I tried both lines that converged at the center of the cylinder that not, however from the same error
 
marcof is telling you, I imagine hoping you would go straight on your own, post at least one image or (drum roll) the file so you can at least know the geometry of the piece.
calandered tube does not mean anything geometrically. Maybe it's an impossible form to develop. . .
then if you hurt a pass, forgotten or left a unnecessary check or who knows what else we don't know.

I mean, you know what? dacce er fail

It doesn't seem difficult for me to understand, for a university student, what I'm asking, and that "I see that I'm following the pass..." doesn't mean anything given the number of variables unknown to us. I am convinced that you, "student studying"[cit.] He understands well that when all the variables of a problem are unknown his solution becomes quite arduous.

ah, but maybe yours is a 2016 start game?
like a prize competition for which we have to imagine which caxxo of geometry you are trying to transform into a developable tube and we must also imagine which among the many options available in the joint folds you flagged or chosen. we also have to imagine if the numerical parameters you entered are compatible with the geometry you want to get etc.
I therefore apologize; after lunch I try to read in the coffee funds.

p.s. we're on the tenth message and nobody understands what you're trying to do. I would ask you some questions. Alternatively, we're all the people who are traveling on the highway.
 
I apologize.
I attach the 3d file that I should convert to sheet metal.
use sw 2015 if the file cannot open it let me know in what format to save it

that is what I followed and that I published you at the beginning of the discussion

ma grazie a nikkke ho risolto il problema
 
the answer was in the #2 post. just select the board (proven personally and works).

as you wrote massive the procedure you had reported in the second post of this discussion works perfectly, so you did not follow that procedure but something else.
I add that we arrived at post n.17 where you tell us that you solved (and thanks to the loop...) without saying where you were wrong.

Maybe you don't understand what these forums are for and you miss the concept of "information sharing".
You don't even know that the answers given to you will also serve others and if you don't write where you're wrong, the next user with your swx prep so he can't just read this discussion and solve it independently, but he will have to continue or open a new one.

In short:

I, I, I, I, I, I, I, I, I, I, I, I, I, I, I, I, I, I, I, I, I, I, I, I, I,

vs

we, we, we, we, we, we, we, we, we, we, we, we, we, we, we, we, we, we, we, we, we

;-)
 
for specific clarity that I referred to the #2 post of the link I reported (see reply #18) and that it reports:

I hope that the answer tonyst has come today because in the first afternoon it has solved the problem and has been able to take part in it; otherwise he refuses to rattle us he took away time and resources as, let us remember the case never needed, it is not a help desk and no one is paid for the profuse engagement.

peace and good
