I would like to modifiy the last vertex of each line feature, if the lines intersect, to copy the depth so that also the connection is made in Z-coordinates. Based on an attribute field there should be determined if the Z-value should be copied or overwritten of it's connecting neighbour. 

use coordinate extractor transformer, change the z value, re create geometry using vertex creator.

 

Negative index positions indicate position relative to the last vertex, where -1 is the last, -2 is second-to-last, and so on.


To replace z-value of the last point:

replace_point
