Hi Rafał, If there is a case where sub sheets can't find their matches in the multichannel tool, this sounds like it might be a bug. Can you post a minimal example to a bug report?
It is not quite clear to me what additional benefit comes from specialized markers for 'exclude from multi-channel'. When creating the multi-channel design, you can already pick and choose which rules areas and/or subsheets are included. However, if you could post a video of your process along with what you are trying to achieve to the bug tracker, this would be helpful in either fixing the tool or fixing the documentation Seth [image: KiCad Services Corporation Logo] Seth Hillbrand *Lead Developer* +1-530-302-5483 Long Beach, CA www.kipro-pcb.com [email protected] On Sat, Jun 14, 2025 at 10:40 PM Rafał Pietrak <[email protected]> wrote: > Hi all, > > For some time now I'm using-and-testing the multichannel tool.
