“Clipper” transformer fails to clip “polygons”,

Hi Jamal,

 

 

In my experiences, the Clipper sometimes doesn't work for ellipses. Similarly, there could also be cases where the Clipper doesn't work if polygon boundaries contain arcs as their parts. I feel it's a bug-like situation.

 

 

As a temporal workaround, try inserting an ArcStroker between the AreaBuilder and the Clipper.

 

But I would recommend you to contact Safe support to get more reasonable solution, sending your data and workspace so that the situation will be reproduced.

Hi,

 

 

I can only confirm what Takashi is saying, the Clipper (as well as some other transformers) has known bugs when working on features with arcs. Unfortunately, some of these bugs are still present after many releases of FME...

 

 

I think the best course of action is to write Safe support and to be added to the list of those waiting for a fix for these issues. Hopefully that will give these bugs a higher priority.

Many thanks for the help.

 

 

 

Sure, I’ll be contacting the FME support to report this issue.

 

 

 

However, I followed the recommendations of Takashi and the results have been enhanced.

 

 

 

 

..or the objects are misaligned, broken etc.

Thanks Gio
