Thank you very much for your remarks !
In order to change these mistakes, I will try to find another drawings than
the ones provided by Boeing...
Indeed, the companies often provide drawings with mistakes volountary...
Consequently, my own drawings (based on them) have the same mistakes...and I
really would like to improve them. So thanks very much.

The link might be OK now, but the drawings sure aren't.

I speak specifically of the early Boeing jetliners, the B-707-120,
B-707-320, B-727-100, B-727-200, B-720, all of which I have flown
in service with Pan American World Airways, and also the B-737 series
which I have not flown.

These aircraft were of what we called the "double bubble" construction.
An upper lobe and a lower lobe pinched together at the cabin floor
line. The above mentioned aircraft shared an almost identical upper
lobe, differing only in length, with the major aircraft difference being
the size of the lower lobe. Externally, the cockpit areas all looked
the same.

I call your attention specifically to the drawing of the B-727-100 which
looks more like a DC-9 with a third engine than a Boeing. The B-720 is
not even close, since it should look identical to the B-707-100 except
that it is 8 feet shorter in length.
