I mean, if you are a good layout guy, you are a good layout guy.
A tool is a thing you can learn on the job. The same principals apply. Want a job lemme know where abouts you live in a pm if interested.
I also understand where you are coming from being a layout guy in the midwest who knows Altium. It seems like all the big boys use Cadence. GE, Northrop Grumman, motorolla, the list keeps going...
I fortunately have the benefit of working for a company that provides me with both Altium and Cadence Allegro.
Allegro is by far a way more powerful tool than Altium. The learning curve is very steep though.
