Does anybody have the autocad drawing of the 737ng shell. I have did have the file somewhere but dont know where i put it.
Thanks in advance

Hi David,
I think there are already several threads relating to this. Unfortunately a good CAD drawing has yet to surface or at least be shared with the community.
Has anyone ever contacted Boeing and just asked for the drawings from the side entry door station forward to the nose?
You might be surprised if you just ask. Who knows?
I have written them on a few occasions asking if theymight have a spare nose section lying around that they did not need but I have yet to hear from them. Never thought about asking them for the drawings though. I did send all the measurements I could find under our files section and on Ian's site to an architect friend who promised to work on them whenever he had the spare time.
It might take several attempts until it lands in the right e-mail box with a corporation as large as Boeing.
I'd probably bypass Public Relations all together and try to get to an engineer or designer. Customer Relations might also be a source.
Without considering company policy, it's just a matter of finding the right person.
It's not like the Boeing 737 is some deep dark National Security secret. Anyone with a nose section could reverse engineer it and/or make drawings from it given enough time.
I agree with most of what you are saying Michael but you also have to see it from their side. Essentially any drawings, measurements, technical information, etc. (while not a matter of national security) are in my opinion not going to be divulged too easily by Boeing or any other company.
You are right, someone with an old nose section or even access to an active 737 could work on getting the measurements and putting these into a CAD program and getting the drawings a lot of us would love to have.
However, it is one thing to know people can do this and completely another to actually give out the design and measurements. Any one can buy an Iphone or any product and take it apart to see the design, measurements, etc. but that doesn't mean Apple or any other manufacturer is going to make it easier by just sending them out.
Of course there may be companies that do this, especially since we are not asking for the designs to make a competing product and you may be right in that it might be easier to get them directly from someone who has access to them, as opposed to having to work through multiple departments. As long as there is no company policy regarding schematics.
And here is the official line on this:
Yet another reason why you either have to find someone at Boeing willing to get you the drawings or put the information we have into CAD form yourself.Quote:

I then went on the contact CAE and Thales and they both said that they simply have to abide with Boeing regulations regarding the drawings.
Sad considering quote, 'By giving measurements to anyone other than a simulator manufacturer, we are putting the Boeing Company at risk'. I left a reply asking what the risk was and that was the last of it :roll:
Well I guess that party's over with.Quote:

Here is a bit of information I dug out of a Boeing 727 reference guide I have.
Each station on the airframe is measured in inches aft of the datum point.
The the 727's case the datum point is 130" in front of the aircraft. This is how long the flight test probe extended out in front of the aircraft during testing. The tip of this probe is '0' inches.
The very tip of the radome is 130" back and is called station 130.
From the radom tip to the the very aft of the #3 window frame is station 259.5. If you subtract 130 from 259.5 you get 129.5" or 10'-9 1/2". This is how long this part of the cockpit section is. Each of the ribs has a station point aft of the datum plane. This only has to be subtracted from the nose datum point and converted to feet and inches to get a measurement.
This will even tell you the spacing of the ribs under the windows as each has a datum reference.
This information is near worthless without addition data from a plan view with the same station identifiers, and a front view as well, but it is interesting to me.
Incidentally, the entire cockpit section as an assembly as mated to the front half of the fuselage goes to station 348.2, just aft of the left side entry door, or 18'-2 13/64"
I'm guessing even if we formed a simulator manufacturer company we would be contractually bound to keep that information confidential. I'm wondering... if someone came out with the CAD drawings (providing them commercially or not), would Boeing push for a cease and desist?Quote:

Boeing is very tight about things like this and I'm sure Airbus are alike.Quote:

You can douwnload the shell dimensions in autocad. They are in my profile ->douwnloads. More cad drauwings will come.
HI thanks for all you have shared, but unfortunately, I don't see the cad file with the shell dimensions in your downloads folder anymore. Any chance you can re-upload/provide this?Quote:

I would be interested too,
Thanks in advance,
Downloaded yesterday, great drawings ?
Hello I am new.However I know there is a cad measurement around.I saw on the "Portuguise 737 project" it is so simple its not funny...its just a paper cut out that you trace onto plywood and cut and bingo you have the ribs or stations,however I need the measurements so i can do the same. I dont know how to work with CAD but does anyone have the cut out paper stencils??Dont throw them away,we can buy them ???
Kind regards Faleolo
I understand that Mike at the Portuguise 737 simulator project has them but I am unable to communicate with Mike.Its simply an extraction from CAD then drawn to scale on paper,then traced onto plywood to cut the stations or ribs.If you see his video its brilliant but how do you extract the measurments from the computer??? only Mike knows that.Not sure if Mike is on Mycockpit but its a great idea as its all exact
Hi Raymond,
Its Norman from Faleoloo.Is what you downloaded the shell cockpit CAD drawings??? What site do you go to to to this?
Regards Norman
Hi Efe Cem Elci,
I don't think we need to worry about Boeing...we are hobbyists and we are not copying to build flyable 737s We are builing replicas privately.I think we should stick to sharing how we build our cockpits.I don't think Boeing would worry too much about hobbyists or Enthusiasts.
Cheers Norman
