@williamatics that reminds me a little of the “ekranoplan” I mentioned once during the vehicle modeling class.
I understand what you mean about the challenge of using only primitives. It’s an important exercise for brand new Blender artists but it’s -hard- for someone used to working in edit mode already. In a normal project I don’t think I ever have objects that I haven’t manipulated with edit mode or at least modifiers in some way.
