so go ahead against 3dcontent central, tracepartsonline and grabcad etcā¦
Just a quick search would have pointed to
Copyright is a legal right created by the law of a country that grants the creator of an original work exclusive rights for its use and distribution.
original work is enough to cover what we are talking aboutā¦
Moreover copyright is strongly dependent of countries and jurisdictionsā¦
In case of a so widely diffuse sw as kicad is, I would not allow to be in the library any 3D model which has not stated clearly a correct license of use.
Yes, that is the naive view, and pretty much 100% wrong, itās a whole lot more complicated than that. āOriginal workā has a very specific meaning in law, and is not the simple meaning enjoyed by lay people. It DOES NOT mean, āanything you might createā.
Did you even read the article I linked?
The important point here is not what we might want to āacquireā from other people. The real important point is that if we contribute our models to a 3D model repo which has a copyright based license such as GPL, that license very probably has no legal meaning. So if our work gets ārippedā off, then we have no leg to stand on. It is very misleading to let people think their model has any GPL protection.
There is no copyright law that covers a functional object I am pretty sure that is true in every jurisdiction, copyright law is fairly well aligned internationally. There are jurisdictions where you get less protection from copyright. Even if a work is subject to copyright, statutory exemptions such as āfair useā may apply.
If you contribute a 3D model of a functional object to a public repository, DO NOT expect it to be covered by GPL, CC or any copyright license
Every lawyer will tell you exactly the same thing, everything else is just popular folklore from people who do not understand copyright law, and have never studied it. And trust me, you wonāt get a good understanding by a quick glance at Wikipedia.
you can bold all your post text, but the final point is that nobody wants to have a legal dispute for what can be avoid with the right premises
Anyway if you want to start a legal dispute with the public repositories that I suggested above, you are very welcome to enjoy your time
The most recent discussion regarding potential IP issues is a very big argument for parametric derived models. At least for the most used packages, non-series/discreet parts should be treated separately.
One of the first questions I ask on starting an engineering project is what standards are we designing to? Electronics is currently a hobby for me so I am not familiar with the various standards bodys for electronic component design. But a quick search indicates that JEDEC has open standards for many component packages.
By using parametric models (of which a large number appear to already been generated/setup) where it is easy to compare a table of the driving dimensions against a table from a referenced design standard, you can quickly make the check for compliance and at the same time the person who developed the parametric model is able to transfer whatever rights are deemed necessary for the parts to be incorporated into the library.
This should cover a large portion of the standard component parts, and minimise the time required to incorporate into the library. The remaining unique/discreet components will need dealing with on a case by case basis. If you can convince suppliers to engage/sponsor with the project and supply models and foot prints then all the better.
These models are/should only ever be used for geometric/visual purposes. If people are running thermal and other simulations then they will be building functionally accurate models for their chosen simulation software.
First: I dislike your way of talking in a public forum
Second: regarding the criticism you made on my tools, I thought it was you that were disappointed not to be able to use a set of tools that thousand of people are using easily
and referring to ignorance, I will let you enjoy yours
It may depend a lot on which deep is your simulationā¦
probably you will need a more specific model to adhere exactly the manufacturer you have chosen with thermal coefficients and more dataā¦
I think manufacturers data sheets are reasonable basis for series parts (parametric) provided that they have data for the whole of the series. Otherwise if there is a source of for series parts that can be built from a dimension table of the variants then it becomes much quicker to check and in theory to get them incorporated into any library, because there is a single reference to check against.
Yes thatās my point, that the models included should only be used for geometric and visual purposes, so slight variation between manufacturers (for a common package) is irrelevant in this context.
From what I understand from the article, the main point is that what you physically create by using the information from a 3D model file, the physical creation is not subject to be copyrighted (it can be however patentedā¦ by some other meaningsā¦etc)
However,
I extracted two main parts I found here interesting for discussion:
Unlike a functional object, a file is just code. And code is generally protectable by copyright. That means the even if the object is not protectable by copyright, the file may well be.
it may very well be that while code is generally protectable by copyright, the code that simply represents an object is not protectable by copyright.
From MY interpretation of the second quote, I donāt think it will be applied on this cases (but I may understand on each cases it can be appliedā¦ just canāt get with an exampleā¦ )
But so, it still looks OK (to me) to license somehow the files (generally the copy / share of the files)
Do you have any suggestion / examples for this kind of license?
Related with this discussion, the diptrace software provides tons of STEP files: http://diptrace.com/libraries-and-3d-models/3d-models/
it would be nice to know/understand what kind of license they are sharing the files. (they provide auto-extract.exe files so I couldnāt extract it on linux)

As I already mentioned I donāt think this kind of license is fine for kicad library, but I think something like gEDA exception could be managed contacting directly FC peopleā¦ many of them are also present on this forum
Anyway this is only my opinion, others may disagree, but consider that my opinion is aligned to what Wayne said few time ago http://www.mail-archive.com/kicad-developers@lists.launchpad.net/msg16679.html
and it is also aligned to FSF lawyers thinkingā¦
so in case Iām wrong, at least Iām in good company
Kemet have a huge selection of detailed models - their entire range it would seem at https://search.kemet.com/component-edge/#/?id=410. No registration required and I can find no specific licensing restrictions on their use.

Any other uses of any of the information from this site require additional permission from KEMET.
Either type a model number in the box e.g. T490A157M004AHE800 and choose 'Expand Details" or click through the ranges e.g. Tantalum > SMD Chip > Consumer. until you find the desired product and the .step link should be obvious. (More obvious than the Kemet licence at any rate! :))
Now I checked, I donāt think there are models for every Kemet device but it is a pretty comprehensive archive.
I would be interested in what Kemet (or other vendors) would actually say if asked (officially) about āadditional permissionā. Its a bit of a minefield though - perhaps I should retrain for a lucrative career as a IP lawyer
They need scaling and rotating and a lot of checking and fiddling with - especially to ensure they are dimensionally accurate which is the main reason for using them. They look nice though.
If we play a bit more with the materials and add specularity values to them we surely can do the same.
Actually, I think @kammutierspule 's material efforts where already pretty good in the regard.
This is a povray render from the STEP model right out of Inventor, nothing fancy reallyā¦
@maui by now should manage to do the same for the parametric models he can churn out of FreeCAD
@John_Pateman@Joan_Sparky ok I found I was unlucky and only some parts has STEP files to downloadā¦ It does not look so ācomprehensiveā to me, but still OK to have a look!
