how can i use the chopper transformer to chop a line at specific points taken from another feature class(this all included in the same gdb)?

Carefully consider the PointOnLineOverlayer -- it feels like it will do what you want. Chopper is definitely not going to help -- it just works on one feature at a time, independent of any context.

Hi,

To be able to do that a relationship is necessary so that the point information can be transferred to the lines and be used by the chopper.

Maybe try the intersector transformer Instead if your second dataset intersects where you want to chop the line

Thank you, it works

yes, I couldn't transfer the points information to the line feature class .... do you have any suggestions how to do that ?

intersector transformer doesn't work because (as I understood) it accepts only one feature class as an input to compute the intersections and overlappings between the feature class segments then gets them through nodes output and the intersected segments gets them in a shape of one segment through the intersected output

Your question put me on the wrong line of thought, the PointOnLineOverlayer as mentioned by @daleatsafe is the way to go
