I think this maybe why!

Of course it’s great for vendor lock-in.

But given how many companies need to work with diverse suppliers, there must be a whole bunch of re-creating models happening. There is no chance that everybody is using the same CAD tool

The big example of this is Airbus on the A380 [1], design offices were using different versions of CATIA, we added some features to STEP to allow wiring harnesses to be modelled explicitly.
