Hi, I'm Pol and I'm quite new to FME. In one task I have created voronoi cells from points that share the same value of an attribute and at those points that have a unique attribute value I have created a buffer of a given radius. I did this in order to create an influence map for a certain attribute.

The problem I've run into is with the overlapping buffers on the border of the voronoi cells.

 

This is the current result:

How can I do it? I've tried the donut builder and the hole extractor but I can't get it to work. Any help is great, thanks in advance.

You can use the Clipper transformer. The clippee would be your voronoi cells, and the clipper would be your buffer.

@ddbrocato It worked! Thank you so much!
