Simple question really (I hope), is it possible to merge two surfaces by a common id? I have multiple surfaces and only want 1 output, they have same id number but I can't seem to find any method of combining them into 1 feature. I am initially using SurfaceOnSurfaceOverlayer to remove overlapping features, but then I end up with lots of surfaces, I want to then join them back together, but neither FeatureMerger, Merger or MeshMerger work. Any suggestions?

try with the Dissolver, setting a Group By on the common ID.
David
Unfortunately Disoolver (in 2013 anyway) only accepts 2D objects, so all surfaces are rejected.
Could the Aggregator be an option? Also with the Group By on the common ID.

U need to decompose surfaces to triangles. Or if u are using surfacebuilder, do operations on the triangle outputs.
Triangles u can clip etc.
When done rebuild them to surface: facereplacer, aggregator and triangulator.
Look at a customtransformer in the store called Surfaceclipper. If u study it, you should be able to grasp the concept.

Gio, I am afraid I can't see any SurfaceClipper in the FME Store, is this something that is only available in 2014?
You're right there is none, thats what i called mine.
But i got the idea from
