bro ! this may be hard to give a detailed jet engine drawing because it is time-consuming to give exact dimensions, but if you want to tolerate the dimension of jet (like rough work), someone can tolerate giving the free jet drawing even also me. otherwise, this may be chargeable
Aside from the "small" facts of the drawings (like that) being a closely-guarded intellectual property and commercial secrets (protected by the numerous patent rights and myriad of other legal instruments), for what kind of "project" would you need a fully detailed (presumably assembly) drawing? Plenty of illustrations available on the Net, some are free to download, e.g. https://www.dreamstime.com/cutaway-display-vintage-aircraft-jet-engine-aircraft-jet-engine-image207718394

It's not just the manufactures that will keep it a closely guarded secret. Anyone that has spent the time to even modestly reverse engineer a jet engine and produce a full set of detail and assembly drawings is not going to just give them away.
I'm not sure he realizes what he's asking for. Or maybe he does and just doesn't want to invest the time to do it himself.
@AKASH KUMAR "this may be chargeable" is an understatement. LOL
I guess, some of the VERY old designs might be in public domain (BMW-003, RR Nene /Derwent, etc), and might be useful (for general principles demonstration, high school level projects etc.), probably on microfilms, preserved & owned by academic institutions, museums, appreciation societies and such, but those are interesting purely from a historical perspective: major advances (accomplished since) are NOT that conspicuous (like metallurgy & electronic components: eg. sensors & ECUs)
