Boeing used to use CATIA, might still be. When I was interning there, I got every available hour of training I could because I heard Chrysler was using it as well to model things like heater/AC ducting. Not hard to imagine they would use it for more than just that.
Funny thing about 3D software...there are multiple uses and each seems to have tools that work better depending on the case. As an example, Revit is the go to standard for Architects, but it sucks for detailing the actual building members for a shop to fabricate them. And you wouldn't use SolidWorks to model a building as it is much more suited to manufacturing complex assemblies, like a camera body or carburetor. And AutoCAD, while it will do 3D stuff, is really much more of a 2D line drawing package. All pointless to the discussion, but a nuance that it seems lots of people miss.
Not schooling anyone, just saying.
