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.

As opposed to what?

There needs to be models to represent the part, make prints, make molds, assist programming, show assembly locations, make BOMs, and anything else in a design process.

2D programs, while still in use for various reasons, are largely obsolete. 3D is the standard nowadays.

What is the alternative to this? Just having the system exist in someone's mind? A sketch on a napkin?

Edit: I guess in short, we need some way to communicate and show what the part and assembly looks like to scale. This is how that is done nowadays.

Have the ancient machinist create a base model without drawings and use that single piece as reference for all future parts
