Find face after boolean

[Konrad162]

Hello dear experts,
I hope you can help me.
With the use of Geometry Nodes, I cut one object with the other using Mesh Boolean.
How can I select the same node flow faces that were created because of this cut?

Hum, you can select intersecting edges but that’s probably not what you’re after,

I’m not 100% sure to understand what is

@Konrad162

same node flow faces that were created because of this cut

Finally, there isn’t a straightforward way, unlike extrude for instance that allows to select each parts of what is generated after the operation.

So it’s likely to involve some cheat to find what you want given the specifics of your scene…

Don’t hesitate to post a blend so we can try some stuff !

Not sure now away from the pc, but I think capture positive Boolean on the original mesh gives the desired result “not”.

Hi,
you could capture a Boolean attribute set to True before the actual Mesh Boolean like so:

@filanek: Damn, you were faster

[sozap]

Well done guys ! I didn’t knew this was possible ! fortunately I don’t use boolean that much since I would have probably came up with something highly convoluted to get a result much worse

Not sure if it works for complex scenarios but alternatively this could also do the job.

This might not even be needed, just my “lack of geo nodes experience” logic -

works like a charm, thank you very much!!
