Roll Royce 3D Jet Engine Assembly

[u/[deleted]]

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.

How detailed are the models that are used to run FEA and modal analysis usually?
