Hi,

 

 

I would use the spatial relator/filter for that instead of the clipping.

 

Hope this helps

Hi,

 

 

The processing order seems to depend on the input order of clipper features, not their area-size. So, if the largest polygon comes first, inside smaller polygons will not be used as clippers.

Hi,

 

 

maybe it is an approach to filter out large areas first (by area size) and then do the clipping.

 

 

Best regards

Thank you for your answers!

 

 

I tried some different settings and it seems that the area which arrives first at the transformer is used as clipper.

 

So for my analysis its a good compromise to sort the features by area-size and route them into the clipper.

 

 

(Its not possible to remove larger areas first, because there are also lines in the larger areas (but outside the small polygons) and they would get lost).

 

 

Best regards

An intersector or LineonAreaoverlayer followed by an spatialrelator.

 

The resulting list will show all the relations between lines ad areas; assuming u have them all named or numbered.

 

And by exposing cardinality u can search for lines (rather then point) relations.

 

Afterwards u can rejoin relevant lines by their name or numberid if needed.

 

 

And clippers has a switch for multiple clippers as far as i know btw.

 

 

btw in fme2012 u have to explicitly use an exposer to expose cardinality because it wont show in te attributes to expose...

 

If ur gutsy enough u can even try out the dim9 relation matrix..;)
