+4Hello,
I want to cut a layer (buffer zone) according to another layer (urban zones), so I set up the transformers clipper but the cutting does not take place and the entities that emerge are the same as at the input (cf. attachment) :
Before Clipper :
After Clipper :
Would you have an idea to make this cutting work so that my buffer zone does not exceed (that it must therefore be cut) according to the urban areas present in the second layer?
Thanks!

Do they also have the same values for that attribute? By setting the group by, you are basically telling the Clipper to only clip Candidates that have the same value for that attribute as the Clipper. Try it without the Group By and see if that makes a difference.
+35Are you sure both featuresets overlap and more likely the error, both featuresets have the same coordinatesystem?
+4The two entities overlap perfectly and the projection system is the same.
+4Yes, the two entities have the same attributes (using the transformers attributemanager before allows this).

+4I just tried and it works, I then added a fusion transformer and everything seems to work as I want. Thank you !
