Hi, I want to identify lines in my data, that have the same x and y coordinates and differ only in the z values. Can someone help me out? I'm new in FME.
Thanks in advance

All of those have functions that will give you what you are wanting to do with varying outputs depending on what you plan on doing next.

You may need to remove the z values for the comparison (2DForcer) then use a FeatureMerger to get the original geometry back onto the filtered data
@tom.p I think @hkingsbury is on the right track. Use GeometryExtractor to preserve the original geometry. Then 2DForcer to drop you Z values. Then one of the options listed by @jlbaker2779 - probably Matcher. Then recover your original geometry with the GeometryReplacer
Hm let me thank you for the replys at first. It seem like the Z value does not disappear after the 2D Forcer. 
This should be the reason why no matches are in the output of the matcher (although there should be some).
Maybe my matcher parameters are incorrect too?:
