Most modern CAD software for PCB design offer arc trace routing or a form of conversion between 45/90 degree angel trace routing and arc trace routing. Despite this, the overwhelming majority of commercial-grade PCBs seem to still be using 45/90 degree traces.- A similar question has been [asked before](https://electronics.stackexchange.com/questions/7913/why-is-there-such-a-strong-preference-for-45-degree-angles-in-pcb-routing). The consensus there is that CAD software is easier to design that way. That question was asked in 2010 and the situation has changed since then, so I do not think that answer is sufficient anymore.
- Are there downsides or upsides to using arc traces in PCB designs as opposed to 45/90 degree angle traces? Are there situations where one or the other is preferred? Is there a reason for the popularity of the 45 degree routing style besides it being the default option in CAD?

Using arc trace routing instead of 45 degree trace routing
Most modern CAD software for PCB design offer arc trace routing or a form of conversion between 45/90 degree angel trace routing and arc trace routing.
