I have points that have no order but need to form polylines based on nearest distance and grouped by a unique identifier. Also being able to exclude points beyond a certain distance. Can anyone suggest appropriate transformers.

Hello @aevans​ I would suggest a combination of NeighborFinder, VertexCreator and LineBuilder. Somewhere in there you will need to sort the points lines based on the nearest neighbor but that is the tricky part. I am having a look into it and will let you know if I find anything suitable :)

Hello again @aevans​  try the following. It will probably need some tweaking for your situation i.e. NeighborFinder distance .

I had to user the neighborfinder twice as it was doing some strange things with my sample data. Other FME gurus might have a cleaner solution.

​Thanks for the reply to my problem.

Unfortunately I could only generate this kind of result below, so I am going to use python and incorporate it into FME, as I know it can produce the desired result.
