+10
here is my problem I can´t get solve:
I try the "LineOnLineOverlayer" but I don´t want to touch the red, blue and green line. I have many lines at the same location with different attributes and nodes (black point in the image). After the transformer, the red, blue and green line have new segments I don´t want.
Thanks for help!

"Clipper" is the equivalent of QGIS Difference, by outputting the Difference between the Clippee features to the Clipper features to the Outside Port
+10Hi @danilo_fme,
thanks for you response. I created 2 shapes, I can´t share original data, but the problem is the same.
The purple shape must cut and delete all lines from the shape "blue_red_green". After that the purple shape replace the space. It is very imported, that the rest of the data from "blue_red_green" is not modify.
I hope you understand my problem.
+10I try to solve the problem in QGIS. The tool "difference" did the job (ArcGIS eraser?). I can´t find a identical tool in fme. :(

Hi @bwn, thanks for your answer. If I get it right, the clipper can´t handel lines on lines, only lines on polygones.

Hi @connecter
Thanks your data.
I simulated here in my machine using first the transformer Bufferer and after the transformer Clipper:
Attached the Workspace template ( .FMWT ). Workspace_Clipper.fmwt
Thanks,

Hmmm, you are right, I assumed Clipper would be able to use lines as Clippers as well. There are then a couple of variations:

@bwn thanks for you answer. I tested a little bit with the LineOnLineOverlayer, but from my point of view it is too diffucult for such an easy task. The problem is, that all lines go to one inputsteam, so the shape "blue_red_green" intersects each other. That is not nessessary. Why is safe not release a simple erase tool?

Thanks @danilo_fme. But when I take the "Bufferer" I change the data and the length is not the same as before. As I manson before, why is there no simple erase tool for such tasks?

@connecter. The Bufferer solution requires End Cap set to "None". This setting should result in a Clipper shape that same length and orientation as the Purple line.
LineOnLineOverlayer is a more general purpose tool to cover a wide range of different use cases, so requires manipulation of the input and output to get the desired result, including using Sorter to change the order that features enter it which determines which Attributes get used first, Group By to restrict which groups of features to compare with each other, and post-processing Lists etc. so yes, it can be a little more involved.

@bwn Thanks! Here is the workflow:
