Hi.

I have these polygons:

I want to clip the big one with the small one and keep the rest. They are in different layers.

I use the Clipper transformer:

- Clipper: layer with the small polygon (DGN)

- Clipee: layer with the big polygon (DGN)

The result should be in the Outside port, but it is in the Inside one. Why is that? I have cut thousands of polygons this way and this is the first time somathing like this has happened.

I can't use the Inside port, beacuse I would get a lot of data I don't want.

Thanks for any help provided!

There is an issue with the clipper that produces these results in some cases which could be the issue. Normally in those cases, rounding the coordinates slightly fixes the issue.
