Hi,

I have two polygon datasets (A and B). Of B I want to keep only the parts of the polygons which are not overlapped by A. Let's call these output features the dataset C.

Additionnaly, I'd like to calculate the area of the C polygons. Ideally, I'd need to know the area of each C polygon. I've noticed that AreaCalculator seems to ouput only one single feature...

Thanks in advance for your help !

Use the Clipper. Clipper input will be A, Clippee input will be B. From the Outside port will be your "C" dataset. From there, you can feed your "C" dataset into an AreaCalculator.

Thanks ! I hadn't seen the outside port.
