Want to make curved traces in KiCad?
The track rounder plugin from KiCad RF tools can help:
I learned about the plugin thanks to this post on Hackaday:
Recently, [Maurice] has released RF Tools for KiCad which include a collection of plugin’s that address a long felt need for RF design. The suite includes footprint wizards for designing mitred bends, tapered track connectors, and arc tracks (radius bends) for RF layout. These tools work by creating footprints, so it isn’t perfect, but it’s a big step in the right direction.
Also included is a set of action plugins for arc track corners, track length measurement, and a mask expansion tool. The expansion tool lets you adjust mask clearances for tracks and is handy for RF layout and for high current applications where you want to layer up extra solder on top of exposed copper tracks. It may also appeal to the artistic folks who want more control over track layout and visual design. Rounded tracks will also be pretty handy when designing flex PCBs. It’s worth pointing out that the arc action plugin will create segmented arcs while the arc footprint wizard will produce a smooth arc, so both have their pros and cons. If you get stuck, there’s an active thread on the forum for help and assistance. Check out the demo video embedded below.
