Good morning to all,

theme that could be interesting. . .

in your opinion would it be possible/fatiable to manage a mechanical design studio only with free/opensource software?

type freecad, calculix, etc.

answers can also extend to other areas of course.

Yes, I think it's feasible as long as it doesn't fit into a design too specific, but only at most.
also you have to take into account the needs of the customer......... If that wants the final result done with a file in the sw pinco format, what do you do?
You say no?
Hi.

never seen an engineering study working with opensource software, at the limit at first you could arrange with trial copies, what I am doing now with ironcad (online activation there is no problem, email-computer-key internet)I guess if we consider how many are the level commercial sw that are proposed in trial version, maybe a year free you go ahead

I use free material regarding the little specific uses: libreoffice, thunderbird etc.

for cad and s.o. instead I use only commercial material as those open source are not absolutely adequate.

I studied it and learned it on soft open, but then I no longer had time to deepen it and then propose it to customers. I suspect that closed software is more productive than the opensource software I used (salome-meca).
 
You have to evaluate how much you use software, its productivity and its cost.
If I rarely use the fem, I can't afford a paid high end software, but I will go to an embedded version or the open source limit.
if instead on the cad step 4 hours a day, then probably the investment of the paid version is repaid by productivity. I do not see any convenience today to use open cad, as their productivity is very low.
Of course, if the studio only gets lost, and the cad uses it twice a month and does not believe to repay the cost of the license, then the open can be a good solution.
of cad there are of all costs, and if a study fails to afford a rhino or geomagic license, which opens to do. but certainly repay the investment of these software compared to the increase in productivity they give is quite fast.

hunting quoto on fem.

thanks to your help I started moving the first steps on salome-meca but then I left everything.
the biggest problems I had in importing the step files or in making mesh.
often the sw did not recognize the geometries I imported and, when it did not trouble, could not mesharle in 90% of the cases.

"payable" software can also meshare the antimatter:tongue:
 
open software requires a very considerable time spent learning on uncertified documentation.

If one starts studying them at university, he uses them continuously for years is feasible. . .

I see them well only in the field of university research where a researcher can study them, turn them back, and implement new functions by programming them.

we only think of the documentation attached: we are talking about hundreds of mega files, contextual help, updates for new functions etc. ect.

the current cad 3d are now mature, for a typical company in the field of mechanics now there is nothing that can be done either in proe or solidedge or other and vice versa.

However learn from scratch to make a single piece a day is enough for everyone, to use them in a professional way with carts, ad hoc configurations, topdown techniques, management together and variants, revisions, families of components.... it is also hard with the commercial cads of which however on the internet you find tutorials and mala parade you can always take a course (which I recommend to everyone).

then there is the hardware problem: already with commercial ones you have to be careful that the video card is certified, with an open source figurati.... turns on w7, maybe on w7 64bit no. turns on w8, but maybe in some operations it crashes and has to understand why (and who you call for assistance?): instead of designing time to do the software analyst without having the skills.

I like to "mantle" with the software, I had a half idea to try wildfire under linux or learn salome-meca.
Then I put it through right away, to do the things done well you have to spend a lot of time.

and I don't think it's a coincidence that the same ptc has given up developing versions for linux.

a few years ago it seemed that linux was approaching the performance of windows, but since seven came out the gap seems objectively to me to become huge again.
 
e la versione di creo free (ptc creo elements/direct modeling express 6.0)? non sembra male se abbinata a uncalculix or sw di fem. . .
 
I also agree that with all 30days trial you can start the first 6 months free (also heading the products, however). and this represents an advantage not recently, I would say.

I do not know the philosophy of all the software houses but I know for certain that autodesk does not allow the use of trial versions for profit purposes. therefore theoretically with trial versions you could not develop any commercial project. . .
...then it goes by itself that it becomes complicated to prove that I am using trial versions to work!
 
but how can you work with software that expire after a month?
What if I have to make a change to work?
What do I do, keep my first job in a cad, the second with another cad? And then I don't get anything back?
or do I export in neutral format, then start from scratch if I have to make changes?
better start with economic software and work on it. sincerely using trial versions does not seem feasible. Unless you reset your pc and reinstall, but at that point it becomes real fraud.
I can use a trial version for a particular job with software that I don't expect to use anymore!
I on these occasions asked for proof and then rent for a month, some house software do. between trial and rent closes the job and you are in order with all
 
yes' some do it wave, and yes' with 30+30 days normally a job will carry it to term, provided that:
1) be a small job
2) you know the sw well at the first shot, and generally it is a new sw, so I would say that this second condition is already impossible alone.

unless you have already used this sw......... so it wouldn't be "new"

Moreover, always theoretically speaking, and to do the pinions, with the 30 days of sw test you could not work, that is you can only try the program, but you could not draw/shape us something that then billed.
I think I've read that the official autodesk policy (e.g.) recites so, others don't know......
Of course it would be difficult to prove that you did that right in those 30 days and with that trial version, but so................
Hi.
 
the point is that with trial versions many times you do not even have at your disposal all the commands so also knowing the sw, for certain processes, you have to study the "escape routes" that eat time.
 
in my experience free software has nothing to envy to the paid one, and also documentation is well done and often accompanied by many more tutorials than the paid sw. the only problem is that software cad free simply does not exist (no, no exists, do not tell me about librecad, draftsight, etc. I said it does not exist).

If you don't fall, tell me what problems are with thunderbird, smath, freemat, etc?

I just don't understand. use trial for profit is prohibited. At that point he uses the smart version, it's more comfortable and do the same crime. Then the magistrate will say "our honor, I have a clean, immaculate consciousness. I never used it!"

the crime is not the same, if it rings me at the door finance and I turned off all computers but:
I have a trial copy installed = nothing happens to me
I have a copy aummaaumma installed = 5000 fine and judge
or
if it rings me at the door finance and I lit the computers and I have an old release installed and more:
I have a trial copy of the last installed release = nothing happens to me
I have a copy aummaaumma installed = 5000 fine and judge
But these things don't get much done to talk.
