When designing a PCB, most of your time may be spent interactively routing.
PADS has always been known for having powerful, yet easy to use interactive routing capabilities to help engineers and designers in this phase of the design process. You need the ability to quickly connect the easy traces (is there such a thing anymore?) as well as be assured that your critical nets with length constraints, differential pair assignments, etc. are routed to their assigned rules. This is just another area where PADS excels!
