Topology mismatch not allowing Reapeat Layout function

Layout
1

Hi all! I’m trying to use the new ‘Repeat Layout’ function but am running into a topology error. I’m not sure what is causing this error. For context:

  1. I am trying to repeat this circuit seven times, and have 7 identical sheets:

  1. I have the layout complete for the first instance, and have generated the Multichannel Rule Areas:

  1. I have all other instances in my layout, also within Multichannel Rule Areas (only showing two for reference):

  2. When I go to repeat the layout, I am met with the ‘Topology Mismatch’ status, and KiCAD tells me 0 rule areas were copied:

I have used the repeat layout function in this same project and ran into no issues. I’m not really sure what to do from here, and I’m sure there’s a simple fix that I am missing. Any help would be appreciated and I can also send the project files if needed. Thanks!

Read this first: Multichannel layout - tool not pasting the reference layout

Somebody else had a problem with “topology”.

EDIT: nah, it was this one: Multi-Channel: I'm getting a "topology mismatch" status when attempting to repeat layout

Thanks for the response! I read that post before posting, but unfortunately, that solution didn’t work for my project.

Please try the most recent “Testing” build. Over 100 bugs have been fixed since the 9.0.0 release

There’s no fix for the “topology” in the nightly builds yet, but we are working on it. In the meanwhile, could you share a minimum version of the project showing the issue? It would help us make sure the fix is working correctly :slight_smile:

Here’s the section that isn’t working, thanks!

Thanks for the suggestion, I’ll try this
