Copyrighting private 3D models?

So one of my friends has a 3D chainsaw that he made out of scratch and only uses it for himself. One of his friends asked if he could have the chainsaw as a reference so he can make his own and my friend agreed to give him the model. But his friend pretty much copied the entire model and didn’t really change anything but the textures and then he told my friend that he’s planning on selling it for money. My friend got furious about it and just blocked him. So if his friend did start selling the model somewhere on a website is my friend protected with copyright laws?


Yes. Copyright is automatic the moment you create something. So long as you can prove that you created (or your friend in this case) created the design, then you can claim copyright infringement.
