This thread is about technique in making a wood model. There are a lot of ways to make sure the model gets it's detail. Each line represents a template. It's a wood model you may cut an airfoil or not. I usually don't. As for the fuselage lines give me a good idea of how many draws with a motor tool will dial in the shape. A guy could easily put 20 hours into the contours of this model. Hanging these models still look neat. Most viewers see the model but not the edges.
