Hello,
What is the trick to create a polygon from a set of coordinates and make sure FME read the points in the order to create the required polygon where _result field can be used as ID and acknowledge the order in which polygon should be created ? I went thru a bunch of transformers, but I did not succeed with any... I went thru several articles from the knowledge center as well, but cannot figure it out. Hope the question makes sense.
Thank you for your inputs, regards.

You want a line builder after your vertex creator
+22Have a try at this sequence:
Sorter (sorting by _result if needed)
VertexCreator (create points from the coordinates, set to Add Point).
At the end this will create a line from the coordinates.
If the line is not a closed line, use LineCloser to connect last to first point.and create an area.
If the line is closed, use the AreaBuilder to create a polygon from the line.

Tried LineCloser but it did not bring any value. I still have just my dots (review screenshot).
I tried to build up the polygon with AreaBuilder, but I do not see any options in the transformer that could make it work in my scenario and tell him which dots it should use to build the polygon (or area).
