I tried to challenge my brain a lot with this one and created detailed 3d model of Boeing 787-8 commercial aircraft. Not pretty accurate, but very detailed model.
Model was created with moi3d v3 CAD software, similar to Rhinoceros3d. Realistic renderings was created with Blender 4.0 version with Cycles render.
There are no textures, every part was created with nurbs tools.
Fuselage jointed with doors and passenger windows, until pilot windows detached.
It is not rigged model, cause I don't have tools for rigging in my modeling software. You can create riggs for elevators, rudder, parts are detached. There are no landing gears for this model, and no interior objects.
Obj file exported as NGONS, that is how I exported it to Blender3d.
If you wish to change something or to export in other formats or less polygons, then 3dm file as native file extension is good to do it. Enjoy my product :)
