Do you know this as a bug ?

Take some model with a zone of needed bridging.

Set "External infill pattern" to "Rectilinear" => Nice slicing with normal bridging
Switch to "Concentric" => The bridging condition is not detected. A concentric pattern is put in mid air instead...

Workaround : place a special process with "Rectilinear" external infill on the layers surrounding the bridge.

That makes sense. It's not easy to do bridging with concentric fill

If you want bridging, you need to use rectilinear fill

Well this solved my question. The bridging test I was working on had bridges so narrow that the perimeter shells took up the whole width and there was no infill. I didnt notice I was on concentric infill. Perhaps a notification or greying out with a tooltip in the "Bridging" settings if you have concentric infill selected would prevent confusion?
