Voyager88, I had a very similar problem when I was create a installation where we were intending to suspend 3000 jars from the ceiling with fishing line. I had to come up a with a definition that would "trim" the line using a given surface. To do this, I created a grid of points above the surface. I then copied the points below the surface and used the Line component to connect the points. This would create a vertical line passing through the surface I wanted to trim. I used the Surface/ Curve intersect component to then solve where each line was intersecting the surface... ultimately creating a set of points on the surface. I then connected these new points on the surface to the original points that were above the surface to create the "trimmed" lines. I've created a tutorial that goes step-by-step through the process, which might help you in your application. The tutorial and source files are located here: http://www.liftarchitects.com/journal/2008/10/12/grasshopper-tutorial-suspended-ceiling.html I hope this helps.
