CAD tools are undobtedly very useful and powerful if used correctly. But
that last qualifier is important ;-). My view is that the use of such
tools increases the 'difference' between good and bad designers, they
make good designers (who know how to use them, and not to trust
everything the simulator says!) even better. And they make poor designers
even worse, bexause such people fiddle on the simulator until it seems to
work, not rralsing the result probably won't work in practice, or any
least won't work reliably.
