[paperPino]

Hi everybody!
As some of you already knows, my paper model hobby is mainly devoted to paper automata and paper globes. Last year, I was asked to design the OGS Explora research vessel, owned by the institution (OGS) where I work. It was a nice experience, and I hope that the final result is satisfactory, though I am an absolute beginner in the field of scale model reproduction.
Now, I would like to design an airplane through views and cross sections.
My question is:
Can you indicate good tutorial(s) explaining how to design the fuselage (but also other parts) by means of cross sections, utilizing a 3d polygonal modelling software (I usually use metasequoia)?

Thank you very much for your help!
