If it was really "True", there would be no 3D models on any website (TurboSquid, CGTrader, SketchFab, BlenderMarket), and any other website on the internet. Most if not all companies don't care, as you are not selling a "Physical Copy" of their product. It's a Digital rendition. This has been the topic of discussion on many Car Modeling forums after the BMW issue (One reason you don't see many BMW 3D models out there anymore). However, The chances of a company telling you to NOT modeling stuff in 3D is very slim. Your Rooms Bundle for instance in my view does not violate anything, even the populated rooms, because you are taking artistic license as well as unless you are using 3D Scanners no 3D model will be 100% accurate to the real-world counterpart.
I think you're wise not to risk trying to sell your digitizations of real world products that are still potentially under copyright protection. Even though the risk might be low that some manufacturer might try to prosecute you for doing so, you have to ask, "Is the risk that I have to retain a lawyer, and incur THAT cost, worth whatever I might make by selling my 3d renders of those particular products.
Unless you stand to make some serious $$ by selling those things, I'm guessing that taking the risk is not worth the benefit.
And, despite what one commenter said, that you take "artistic license" is not enough to protect you from copyright
If you were making an editorial statement about your work, it might be protected. For example, if you were re-creating something to argue in court, or in the media, that 3D renderings were NOT simply "copying" someone else's creative act, and making money by selling copies, that would be different.
Anyway, love the work - good luck with whatever you decide!
Ferrari or Lamborghini made a NFT artist take down some of his pieces for sale for something similiar. Maybe if you change the name of the product you can get away with it.
I found this link talk about 3d digitization
thank you for making. 😭
Actually, you are doing them a favor by modeling their designs because you are making them more popular, especially if you offer the 3D models for free. People who work in architecture will need the real models sooner or later and will buy from the real manufacturer. If it bothers you so much, you can just change the names of the 3D models to something else since thousands of models look exactly the same. In the worst case, Gumroad will ask to unpublish the models and that won't happen, so no worries!
this what I'm going to do is to remove the brand name from models to not have tradmark issue, this what happens also in film industry when they use a real product like apple and a car, they hide the logo
