Boeing uses Catia, AutoCAD and Rhino. Catia for assembling the airframe,
AutoCAD for drafting at the aircraft modification facilities, and Rhino for
surfacing, scanning, file translation, scanning and converting point clouds,
and a lot of custom stuff. They have a lot of custom stuff written that
runs on top of Rhino. A lot of software is out there that is a custom
interface that is build on top of Rhino.
You wouldn't design the whole aircraft in Rhino, but you'd use it to solve a
lot of problem areas you can't do in Catia.

I was under the impression Boeing used a somewhat homegrown solution because
of the millions of parts they have. I don't remember the name, but I recall
it beginning with an "A." Any truth in that?
