Posted too soon, you only want the attributes that pass through the failed port.

Hi,

 

 

The AreaOnAreaOverlayer transformer might help you.

 

This transformer splits input areas into overlapped parts and non-overlapped parts. And each output feature has the overlap count attribute (named _overlaps by default), so you can test if the feature has been overlapped or not.

Thanks to you! I did it with Buffer + AreaonAreaOverlay + AttributeRangeFilter!

 

Have a nice day! Cheers
