Where can i find aircraft blueprints for study purpose? I'm a 3D artist and i want to start my new project. I'm going to create an exact model of the Embraer 190 aircraft. I need this for my graduation project at the university (I chose such a project, there is much more than just modeling, but this is the first step). But at the zero step, I was faced with the fact that there are simply no free blueprints in the public domain. There are all sorts of approximate schemes of the aircraft, but they can hardly be called accurate. Even in the manual from Embraer, only exemplary drawings.
Where can I find such things? I am ready to buy them, if necessary.
