I have 2 datasets of points created from the vertex extractor transformer. The 2 points have the same X, Y coordinate but differ in Z. I want to create vertical lines between these 2 points. I think this should be possible using the vertex creator transformer with 2 transformers after each other but can’t get it to work.

You can use a LineBuilder to do this, extract the coordinates of the points into attributes if they're not already stored as attributes then use the x and y fields as a group by
Thank you. I can't find the ''Group By Mode'' in this transformer. How can I apply this setting?

Unless it has changed on more recent versions, if you tick Group Processing you should see the option
I don't see the option. For me there is a ''Complete groups'' parameter at that spot.
But it works, which is great 
However, it won't process vertical lines at intersections. Do you have an idea why and how I can generate vertical lines at those spots too? Multiple vertices at those intersections may have something to do with it? I included an example in the picture.
