Basic question: How to extract nodes from polys ?

Hi,

 

 

This simple task has been stumped. I'm trying to extract 3D nodes from 3D polylines and 3D polygons, to be stored as point features in a separate dataset..

 

 

I've tried TopologyBuilder, GeometryExtractor and a handful of other transformers, but I can't seem to find the right combo.

 

 

I'm sure it's quite simple, but I do need advice on this.

 

 

Cheers.

Hi,

 

 

if your question is how to convert all polygon vertices into points, try the Chopper with "maximum vertices" set to 1.

Btw, if the result isn't as expected, consider trying a GeometryCoercer with "geometry type" = "fme_line" before the Chopper.

Spot on David :-)

 

 

I knew it was as simple as that.

 

 

I appended a GeometryFilter, outputting only POINT, and it worked.

 

 

Cheers.

...or an intersector and keep the nodes
