adobe-autocad

The closest that I can think of (and it's not really close) is Photoshop-Extended for 3D work.However, it is more a 3D "painting" program (at that level, as it does so much more, but not with 3D), and not a 3D modeling program.

As for AutoCad, I can think of nothing.

Still, I would post your question to the Creative Suites Forum, and see if others are aware of programs, in the Adobe lineup, that come closer to what you want.

Good luck,
