Let me ask a simple question from the perspective of a plastic scale modeler and model manufacturer. Why would you want to use them? That would be like using third hand information. The plastic manufacturer goes out and researches and gets plans and then translates that to a 3D form. All of those steps could be misinterperted. Case in point. My company manufactures 1/24 scale WW1 kits. The first project was a Pfalz D3 done from very well know plans and drawings. Very complete model with full cockpit interior. It was not until after release that a very prominent WW1 historian from Windsock reviewed it and said that the fuselage was too short. The plans were off! I Won't change it now. I would have to change the tools, redo the interior bulkheads as well as redesign all interior parts to fit the new parts. I realize my company is obscure, and many manufactures today are using state of the art technologies but that does not chande the facts that they can get it wrong. Revell came out with a Fokker D7 about 10 years ago that was so bad that building it correctly to scale was more work than doing it from scratch!
