Hi I am attaching the file.I have instance lines to particles.My question is that I want the lines not to go beyond the -y.every line has to touch the display grid

Hi. There are quite a number of ways to do this actually.

1) Clip SOP to clip the line below any threshold (assuming it's okay to just chop the line

2) Find the distance at Y to threshold, then ensure that the line don't scale beyond that limit (either using scale attribute, or copy stamp)

3) Limit the Y distance (either using scale attribute, or copy stamp)

... these are just a few ways.

Hope this guide you to the result you're looking for tho.

Happy Friday Night.

[Hello world]

any ideas why my setup is not working? is that the right way to approach that?

As alex suggested there are many ways. But looking at your file.

you might want to limit the template points that are going below 0 in Y.

after the xform, append a point sop with expression max(0,$TY) in position ty.
