Hi,

 

when I apply the sliver remover after an areaonarea-overlay I noticed that arcs get dissolved.

 

I would like to remove slivers but keep arcs as arcs.

 

Repair method is set to "longest boundary".

 

It seems even arcs get dissolved (turned into line segments) for areas/arcs where there is no sliver.

FME 2017.1

 

Is that behaviour as designed? Did not find anything about in documentation.

 

Thank you, Rob

Hi @rob_z,

In FME 2018, the SliverRemover has been replaced by the AreaGapAndOverlapCleaner, which uses a different (and better) algorithm, and retains the arcs. You can download the the FME 2018 release candidate from our download page.

yes, it strokes the arcs. Maybe use a geometryextractor to keep them (or an arcproperty extractor). Rebuild or reinstate the arcs after the sliverremover.
