I have made a tutorial for airliner cockpits. step 1:put 2 fuselage blocks and 1 fuselage cone together. After that put 1 rotated fuselage block and 1 rotated fuselage cone on the top of the middle fuselage block. rear fuselage block has 2.5 length middle fuselage block has 3 length fuselage cone has 2.5 length. step 2:rear fuselage block :4.25 W,1.5H forwards 4.25W, 1.5H middle fuselage block 0.75 rise forwards (fuselage cone) :2.75W,2.75H. Main fuselage to corner style circular. After that make the fuselage block as cockpit backwards to 2.5 W, 1.5H forwards :2.5W, 1.25H fuselage cone on it to 0.5 length and 0.5 rise.corner style to curved put a cockpit block on the fuselage block as cockpit. step 4:rear fuselage block to 4.25 W, 4.25 H forwards and backwards. Middle fuselage block forwards to 2.75 W and H. fuselage block as cockpit to backwards 2.5W, 2.75H forwards: 2.5 W, 2.5 H cockpit fuselage cone to 0.5 length and 0.25 rise. you can also put the cockpit block into the fuselage cone. you have to make the fuselage cone length to 0.25 then put the cockpit block on it and then make the fuselage cone long again. or you can use the finished cockpit.
