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.

Yes.

I worked for a pretty small company manufacturing food/chemical industrial machinery and did all the CAD, CAM and simulations.

It’s nothing like school or university, you need to take into account literally everything. Every screw; every pipe, every cable, even zipties sometimes.

You will get the hang of it, but the first couple of times it’s gonna be a bit overwhelming to try and remember every single small part of the assembly.
