Hello,

Let's say that I have one big polygon A and two smaller polygons B and C.

One small polygon B is fully inside the big polygon A and the other one C is on the border of polygon A.

I need to clip them B and C from the big polygon A.

I use donutBuilder and for one small polygon which is fully inside, I get a good result (big polygon A with a hole B).

The other polygon C which intersects the border of big polygon A is clipped from the big polygon but the part which was outside the big polygon remains as an object. How to get clean cut on the border?

Hi @kbachmatiuk, consider using the Clipper instead of the DonutBuilder. Send B, C to the Clipper port, send A to the Clippee port, and take the resulting feature output via the Outside port.
