How to connect lines between two 2D populations

I’m new in parametric design and i can’t find how to make one thing. I have made two 2D populations with the same amount of points but in different values of Z axis and want to connect them with lines, but when i try to do it, i just can connect one.
Someone know if it’s possible to do it?

Thanks in advance.

Nevermind, i just have found a way with simple line. Just connect one population in start point and the another in end point!

Welcome to grasshopper! I hope that all your solution may be so simple. :smiley:
