Is there a way to change a net class width and have the corresponding traces change? I’ve tried to widen the traces for a net class, but traces already created using that class don’t change. Is there an update from net class operation?
I don’t see how KiCad could do this in all circumstances since changing the trace width could require rerouting due to clearances.
- Select a single track segment.
- Right click and from the popup menu: Select / Select all tracks in Net.
- Press e to edit the properties of the selected track segments.
- Turn on the Use net class sizes on the bottom of the window.
Despite what the elder cat says, you can use either what paul says, or Edit → Track & Via Properties. But naturally you may have to fix the problems caused by this.
You can also use: PCB Editor / Edit / Edit Track and Via Properties. This has several optional filters you can enable, such as select a single net, or a single netclass (or act on all nets on the PCB).
And of course, if this makes tracks wider, you will create (lots of) DRC errors you have to fix manually.
You see, my reading of the question was is there a direct link from the netclass settings to the existing track widths. This is not provided for in the UI. Of course manual intervention either en masse or per track is always possible.
The elder tree also read the question the same way as the elder cat.
Elder minds think alike???
I was able to do this editing the Track and Via properties. Thanks! In my case there was no rerouting needed. There was room available. It’s why I wanted to widen them as much as possible to reduce current heating.
Thanks for the help!
