How to use loft with 2 sets of lines (connecting two lines at a time)

Hi, new to GH, and still trying to learn, I have 2 sets of lines and I want to create surfaces between each two (one from bottom one from top), and I am not sure how to do that. I have attached an image showing what I get when I use loft, and what I am trying to achieve. Thanks.

Are you looking for ruledSurface Component?

That’s why simpler than I imagined. Thank you.
