"Where is the CAD?"
Pro Engineer runs fine, has a native Linux version. Currently experimenting with BRL-CAD - US Army's CAD system, it is GPL and runs natively. Blender is pretty good for drawing stuff too.
"Where are the engineering aps?"
ANSYS and Fluent, probably two of the biggest engineering applications around, run natively and are arguably faster and more stable in Linux.
