KiCad doesn’t support bezier curves for its traces. I don’t need them, but I want them. PCB art is a little tedious to with the tools, too.
So I wrote a plugin to integrate Pcbnew with Inkscape.
Start and end :
I wrote it really really quickly without much testing, so there is a huge list of unimplemented features and undiscovered bugs. But for the most part, this is supposed to be a seamless PCB->SVG->PCB conversion tool, so you can draw anything you like on your PCB, on any layer, and jump back and forth between the two tools.
Give it a shot, submit issues / PRs, and do cool stuff with it. The world is your oyster.
The codebase is a bit of a dumpsterfire. Maybe that will improve, in the future.
I’ve run out of time to work on this for a bit, so things like complicated SVG parsing isn’t something I’ll implement for a while, but PRs would really help!
