Hi everyone,
I’m new to grasshopper but super excited about the potential of this magnificent tool!
I am trying to model water management cut layer, but I have difficulties to find appropriate tools to do the job.
Goal is to find sideways nearby curves and set their height to same height as lowest curve in group (to get all curves at the bottom so to say)
I tried perp frames and other ways around but feeling like I have been thinking this over and over without finding solution to problem 
Any wisdom in here
