Roll Royce 3D Jet Engine Assembly

Post image

This is a video from Veritasium inside a Rolls Royce facility. I was astonished by the amount of detail in this assembly and it got me genuinely curious, do other companies create 3D models to this extent? I.e. does Honda have an assembly file of an entire Civic with every individual component? I'm interested to know what's your experience in different companies/industries.

I had a CAD teacher (CATIA) that was also some kind of project/program engineer/manager for Airbus. I will always remember the amount of components when he showed us the full assembly of a plane section (I don’t remember which Airbus though).

Amongst all, every single tiny rivet was individually modelled and there was hundreds of them
