the objects in figure 3 and 4 models and assemblies in a few days following the basic tutorials found within inventor. other objects are made with the sheet module, which I personally do not know, but I believe that in 1-2 weeks of “study” you could become quite operational on that too. Of course, I'm telling you to copy an object you see in the photo or you're actually underhanded. When you have to think about it, you are another pair of sleeves: you have to have in mind in advance functionality, thicknesses, bulk and feasibility before even taking the mouse in hand. but I see you determined and I think that for a simple carpentry it can come to head even being novice of this world.

I believe that all the parametric cads have the tools to derive on the table a thread in standard (because you do not come from the mechanical field I do not assume that you know that a thread does not put on the table drawing it physically .. there is a graphic representation in norm easy to identify even if you are a boy of the technical institute). Clearly those of the autodesk must also sell autocad and therefore make you pass it as unpredictable to do things 2d.. but now from a good 3d pull out perfect boards.

Let's say that I don't have to copy objects that I have underhand or existing but design them from scratch. will certainly be similar in appearance but nothing existing unfortunately!
So you say that with a 3d software you can still manage the technical design well? or would it be easier to do it in cad and then import it? both programs pull out ready files for delivery to a cnc cutting lab or need further steps?
In the meantime, thank you very much!

 

[Alex_M]

is a thing that makes little sense because inventor already has its own library of all, or almost, standardized standards. what does not have them on the net on sites, such as tracepart, where there are thousands of standards in 3d or 2d. other site where you find models of various kinds is grabcad.

Ah great! At this point I only ask myself, starting from scratch, which is the easiest to learn or use to realize my project, or rather, which is for this type of use the correct procedure to use!

 

[MassiVonWeizen]

you have a friend who has them all, let him explain which is better and which easier to learn. And maybe she even shows you what you can do with each other.

 

[Alex_M]

Of course I will, even if he is in the first arms also being a few years younger than me and having just embarked on this path of studies! meanwhile I wanted to understand something more!

 

[exxon]

I would like to point out that I am completely acerbic in using these software but I have in mind to make two projects.. .

... being a project that I would like to bring to a next level of the simple hobby.. .

Of course, I confirm that I have no competence in this matter, in technical or design. . .

what I miss are the technical skills of design ... for this I asked, because of the work I have to go to do, what program I should like to deepen and why!

Let's say that I don't have to copy objects that I have underhand or existing but design them from scratch.

I know that it will seem madness to you to try something like this without skills, but I'm just trying to understand something about a totally new world to me, so I ask everything that goes through my head (although risking to look stupid) to people who know it infinitely more than me just to try to learn!

Yeah, learn. learn how to design. interesting thread. . .

Now, according to you, because an engineer has made the deck for years and years and years to study theory, materials, procedures, methods... You think he did it because he didn't spend anything, and he had so much time to throw, or did he do it to learn how to do what you're trying to do?

no, because in the first case it would have been a pyrla to use free time to study ten hours a day, while in the second case it would have been a pyrla because with a cad you do everything and you do not need to know what you have to do. I mean, an engineer is in fact, and still a pyrla.. .

in the last post of other threads it has been learned that an engineer must design "a caxxo" (another user quote), and that the analytical approach to design is a waste of time because to be understood only as a method to show others that you have longer (another user quote). your request perfectly matches this "two point zero" vision of design: no longer the application of interconnected notions learned in the course of years of intense study aimed at achieving a unique capacity, but the use "ad cazzum" (this is mine, it is not a quotation) of one or other of the modeling tools made for the engineers "one point zero", the old ones, the ones now obsolete.

Ultimately, we can still be happy: for now, between 3d printers, various arduini, quadricoptera and robots that speak and smile, it is only our profession to be sputtanatanate. the real problem will be when doctors will suffer the same professional oblivion that we are undergoing now: what are six years of medicine plus five years of specialty when everything is on the net? If you have an iatale hernia anyone, after ten minutes of internet, can solve the problem. You don't have to go first to study mitochondria, do you?

So, go, you who have assembled so many pcs, design your home, one program is worth the other. Do it with your student friend who has all the licenses. If it doesn't cost you too much, put the result here, I'm curious. I am because when I did my first printed sheet metal project I made such a figure of merxa (if you use the 'x' you can also write the words "strong", right?), which still burns me. I am curious to see if the mountain of absurdity that I had done depended only on my inability, or on the fact that instead of assembling pc I had spent six years of my life trying to take a degree.

I wait.. .

 

[welcome to the machine]

the files that you have to pass to the laser cut cnc you can get them also from a cad 2d, because the laser cuts a flat figure from a plate of sheet thickness constant, obviously flat.(there are that they also work on canned or tubes, called laser tubes, but let them miss to not complicate too much the picture). for this reason the path you have to pass to the cnc of the laser cut is purely two-dimensional.
but:
you don't have to make some flat pieces, but pieces with folds. holes or windows are not a problem even in 2d, but think of folds.
you need to know exactly how the sheet behaves (what? I do not speak only of the thickness but also of its ductility/elasticity) during and after the bending, in order to be able to develop an object made by bending. think only of the holes, which are executed before the bending and after the bending they must be, e.g., aligned with those of the opposite face. establishing the position implies knowing exactly how the sheet will deform on the fold. this is only a very trivial example of the problems that must know who does the "sheet" (I call them so, but with much respect) .

so if you want to give your supplier the developments in plan of your pieces to cut and fold, you have to master these arguments and many others (if I make a hole too close to a fold, the fold will go looking for the hole, it doesn't bend where I hope... ). the most evolved cads have the modules for bending, which slowly return the developments of the pieces you have shaped in 3d, but it is not that if they see it alone, the upstream knowledge is however indispensable.

I, for example, send to my sheet metal solids 3d and then he "passes" them with his folding program and, if he has to make changes to make feasible (and stable after the fold) the caxxates I sent him, he calls me to tell me " Look that you can't do that, that other one doesn't stand a squadron, here I still have to make you a chord like this etc. " then if he fixes them and I say thank you, because it is his job and I do not have the presumption (or the need) to learn it.

I do not want to discourage you, indeed I like your "knowledge" spirit, but find a second friend of the sheet metal, or prepare dozens of pieces to throw before making them come as you see them on screen.

x exxon
the quote of the "who has longer" perhaps refers to me, which I used in a discussion where dissent from the ways of those who were lighting it too much and I certainly did not refer to you. I did not speak at all about the lack of an analytical approach to design. I, on the contrary, if I were able to, would try to analyze every little thing of a project, find the laws that regulate the events that I want to get and apply to the various cases, in order to increase to the maximum possible capacity of prediction. both to limit errors and, above all, to the satisfaction of being able to tell myself "I am what works exactly as I had thought and calculated and if I want to change this x data and I will get y on the other side"maybe I knew how to do it all the time, so figure out if I doubt the absolute value of study and knowledge. I consider myself an obtorted practical neck, forced to be by my ignorance.

I apologize with the oct and with the others for this divagation, but if I can help to keep calm exxon, which today has woken up wrong, I sacrifice myself in favor of the community!

exxon joke, now you know how much I respect you, even when you polemizzi.

 

[meccanicamg]

Good evening to all,
I hope I have taken the right section!
I would like to point out that I am completely acerbic in using these software but I have in mind to make two projects and I need to understand which program to start studying to achieve what I have mind!
I am a computer enthusiast and I need to design and draw a case per pc a little particular, consisting of various pieces and then let me cut it to the cnc.
I need to draw the various sheet metal parts with related hooks, folds, holes with thread and inks.
I was wondering which program is most suitable for my purpose and I was evaluating inventor, but honestly I don't know if it then allows me to pull out the ready files for the cnc or I have to pass for other software. the thing that attracts me particularly of inventor is the possibility (correct me if I am mistaken) to draw the pieces and then “assemble them” and see if they match the various holes, the pits and the various screws, as well as to see visually how the finished project would come. I was seeing autocad and autocad mechanical... I mean, I'm in the high sea and I hope you can direct me!
thanks in advance,
alessandro

Hi alessandro.
I read a little all the posts here and sincerely I can give you an overview. I don't know what technical knowledge you have on plates, cooling etc.

- all 3d cads can provide universal step format to pass it to numerical control machine tools
- all 3d cads can also table 2d developments and save dwg or dxf to pass it to laser cutting machines and similar
- your friend could help you both to think about technical issues and how to use cad
- after years of professional use of cad 2d/3d I can tell you that freecad is becoming a very useful tool, convenient, free and evolving and you can use it quietly for such works and you can integrate also with cfd of third parties, maybe free and get thus a product comparable with commercial ones but to zero euro

 

[exxon]

[OT]

the quote of the "who has it longer" perhaps refers to me...

Naaaah... I wasn't referring to you: I was comparing the "late b", because I was officially resumed for recommending someone to go to study, while there are moderators who define "supercazzole" other users' interventions... before being accused of using a language not suitable for... community, I preferred to indicate certain locutions as quotes.

about waking up, it can be, but if someone dedicated their lives to the profession that he does and then reads that they are all bullshit and you have to hurry without so many calculations... Even if he didn't wake up wrong, well, he'll be right back.

[/OT]

Mom. @exxon He didn't say he wanted to industrialize the product.. will try to draw it and make it, it will mistake bending rays, bevels, fittings, holes and sunshades, patience! He will try again and correct himself from whom he will give him a hand.
It is not that if the walls of your house you whiten them alone then we are experiencing the professional oblivion of the profession of whitening. . . .
is only a hobbistic attempt of a willing person, who heaviness ..

Okay good. Did you vent now?
I don't know who you are, what you do in life, and I don't care. In the years of people like you I have met so many, that instead of giving a hand in a constructive way they waste their time trying to break up with their presumption anyone trying to approach their world somehow. when years ago I approached the world of photography and post-production, people like you told me the same things you told me. I screwed up and I put myself in front of photoshop where, to this day, forced to go wrong and try again I came to have a very good knowledge. If I had listened to those like you I would have stopped there, but fortunately I don't have this character.
I entered this forum at the tip of feet and in the most total clarity and humility on those that are my technical knowledge about it. I never said to put myself on the same level as those who studied us years. I never said that just a tutorial on the internet to have these knowledge that so many thousand.
But I don't allow anyone else to treat me like this. If you woke up wrong today is not my problem and I will not be your scapegoat. I don't think I've said to claim something or less than wanting to design a satellite, I just asked if it was possible and, in case, how to make my own project. I don't steal anyone's job because I'm not.
You would have done no doubt more beautiful figure and would have seemed smarter if you had used your hard-working professional experience to advise me, warn me about those that might be the limits or problems inherent to what I want to accomplish, instead of criticising and firing at zero with a presumption and arrogance never seen, bringing a series of silly examples without head or tail.
kindly, unless they are constructive things, your quotes, criticism and assumptions keep them for you that they don't serve anyone. I have always used peaceful and respectful tones, I demand the same treatment.

 

[meccanicamg]

freecad with its module Sheettal You can do nice things and discreetly done well.There are also specific tutorials for using all freecad modules.
beautiful of this software is that at the development of it there are avid obediences and agguerriti professionals.
there is much interest because you can implement the functions to create a real production system.
more people try it and more people could be interested in software development and make their contribution.

on the forum we have helped several users prepare and study their projects and we have them here online. some have been built and others have stopped to the project but all this is important because technical problems and solutions emerge, deepens etc.

 

[exxon]

Okay good. Did you vent now?

just to point out that I didn't insult you (as you did several times in your post) and that as I don't demand anything from you, you don't even have a title to demand anything.

everyone is free to express their opinion in respect of others, and for this reason it must not ask for permission. I've expressed mine and I don't see where you'd be disrespected.

I add that I don't take it when the others insult me, you can continue.

If it doesn't bother you, could you answer the question I asked you?

 

[Alex_M]

@exxon

The whole post was an insult. your tones first.

everyone is free to express their opinion in respect of others, and for this reason it must not ask for permission. I've expressed mine and I don't see where you'd be disrespected.

sacred. but you said well, respecting others.

I add that I don't take it when the others insult me, you can continue.

I do. I will not tolerate any lack of free respect.

If it doesn't bother you, could you answer the question I asked you?

What is that?

 

[meccanicamg]

That's enough! Let her out in private. no one cares about all this personal and behavioral talk.
the forum is made for technical things and now I am annoying to read useless things.

@welcome to the machine

so if you want to give your supplier the developments in plan of your pieces to cut and fold, you have to master these arguments and many others (if I make a hole too close to a fold, the fold will go looking for the hole, it doesn't bend where I hope... ). the most evolved cads have the modules for bending, which slowly return the developments of the pieces you have shaped in 3d, but it is not that if they see it alone, the upstream knowledge is however indispensable.

In fact, this is something I have to take into account in the design phase. Thanks for pointing out. I think, however, that holes very close to the bending are not there or try to limit them to the minimum. and in any case, the inner plates that must be under bending should not be too thick to be deformed to the bending... At least I think...

I, for example, send to my sheet metal solids 3d and then he "passes" them with his folding program and, if he has to make changes to make feasible (and stable after the fold) the caxxates I sent him, he calls me to tell me " Look that you can't do that, that other one doesn't stand a squadron, here I still have to make you a chord like this etc. " then if he fixes them and I say thank you, because it is his job and I do not have the presumption (or the need) to learn it.

I do not want to discourage you, indeed I like your "knowledge" spirit, but find a second friend of the sheet metal, or prepare dozens of pieces to throw before making them come as you see them on screen.

no but what to discourage, indeed I repeat every challenge attaches me even more! I did 50 minutes on the phone with an architect working in a design studio and told me the same thing. I'll take it!
@meccanicamg Well, he solved another doubt. thank you! at freecad I took a look, but I prefer to print the work on inventor! I’m slowly understanding what critical risk of meeting, see bends and more, so try to minimize errors. even if, unfortunately, I put in quote some beastly error, some invocation varies and the having to remake more and more times a project. in addition to all problems in the initial phase only to understand the operation of the program. I'm not in a hurry.

 

[MassiVonWeizen]

the sheet bending speech is complicated and also on small thicknesses the deformation in bending phase, the infamous factor k widely debated in the forum, can be important, especially if you have to make precise recesses also for aesthetic question
but deformation can only know who makes bending because there are too many variables that cannot be defined in absolute; without inconceiving that each sheet of sheet is slightly different, different deformations are made according to the material, thickness, bending quarry, bending tool, press force.... so you usually make the 3d or 2d model of how it has to be finished and you pass it to the lamierista that will change the development to get the final result and will signal any criticalities. important is to accurately specify the material, not just say stainless steel, because they can require different developments

@exxon cad3d.it has existed for over 20 years, if you continue in this way you can run all the members in a few months!!! !
it is not possible to tolerate interventions such as the above mentioned and others, If you don't want to make a constructive contribution to the discussion...... avoid responding.

 

[marcok625]

ciao @alex_m, I admire your enthusiasm, do not lose it and you will see that the results will come.
the last advice I would like to give you regarding the choice of cad is to choose a cad that has many videos of examples and exercises.
as it happened to me when I started with arduino, I made myself a culture with all the videos on youtube and they made me understand very and very quickly. so if you choose a cad where many users post instruction videos or exercises, you will see that even alone with tenacity you will learn what you need for your mechanical projects.
Hi.

 

[Alex_M]

@marcok625 Thank you so much! in fact I preferred autodesk products also for this. being the most used is full of tutorials of all kinds that at least can give me a concrete basic idea!
@massivonweizen This thing about the folds is a beautiful bitch and I have to understand it well. Does the program based on the chosen material have a minimum calculation in this regard?

You were referring to the discussion of the tank I imagine. . .
I noticed that when you start making a speech a bit technical/analytical come the usual cad cellarers that solve everything with "but we look so, let's put it so more or less, we always did so ..."
