+ +A planar coil is a coil that is made from flat traces in some printing process like PCB or IC manufacturing, instead of +being wound from wire.

Their layouts are directly generated, without the use of polygon +offsetting. Windings are efficiently approximated using circular arcs. The circular coil layout code is solid, and +contains decent (albeit not infallible) parameter sanity checks. Its main limitation is that sometimes, clearances can +be violated a bit. + +The arbitrary shape code path is less stable, and produces faulty output in some cases. The most common error is +crossing traces near the first vertex of the polygon when the polygon has highly convex or concave parts. I'm still +improving this code path, but as long as you check the output, any errors it produces should be easy to fix by hand. + +If you would like to contribute, I'd welcome any ideas on the arbitrary shape code path. I think there is no single +optimal solution here, and a generic algorithm that can be adjusted to favor for instance shape accuracy versus winding +smoothness would be nice. + +All project links are listed on `https://jaseg.de/projects/kicoil/ `__.
