Hi Charles,

you can try a donotholeextractor to separate outer and inner rings.
Then put the the outputs into a geometrycoercer to force them to "fme_line"
so you get the rings.
These rings can then be written to OGC_WKT (which is a text description of
the geometry) or you can try a put a chopper (value 1) behind it to get all
the vertices as points. You can extract their coordinates into fields with a
coordinatefetcher and put the result into a CSV-Writer.

Greetings,
Jeff

  How do you extract coordinates of inner rings and a out ring of a donu
hole type of geometry to a text file? what transformers are available
for this task?
