I am a design manager for company that makes automotive chassis components. I actually design the components/sub-systems, but I 'manage' many programs at one time. I work with the CAD systems:
ProENGINEER - The ax that I wield
Unigraphics - OK
CATIA V5 - Very disappointing
CATIA V4 - A dinosaur that I am waiting for to die
I-deas - The bottom of the septic tank
