This is the concept art for my Airship model. As an engineer, I tend to think in terms of layout and general sizing, so, I typically start with a three view first before doing anything else. In this case, I didn't even bother doing an isometric or perspective drawing, and just jumped right into blender.
This was done in painstaking detail. I attempted to cross-reference every feature of one view to every other view. The result was a set of very easy-to use modeling sheets when it come to actually modeling the airship in 3d.
Nice model sheet!
This would make a good build!
