I didn’t find a better title, but here is the idea: when designing a circuit, you often have to do repetitive work. Example: you have to design a mixing console. Let’s assume its’ not modular, but on a single board. You will probably design one channel, then repeat it. But with the possibility to design a kind of module, route it, define its global IOs, then it would be possible to align pre-built modules on the PCB and save a lot of time. Is this possible in Kicad?
The Replicate Layout seems to be a quite powerfull script.
Alternatively you can layout a section, then block select it and from the context menu (Right Mouse button) / Select / Filter Selection, and then only include Tracks & Vias and copy them to the other PCB locations, and then place the components on top of the copied tracks.
