In this episode, I am sharing my ”solution” to this little Q&A thread at SVerchok github post thread:
https://github.com/nortikin/sverchok/issues/3337

Dave asked on how to make stairs like structure design using parametric nodes of SV. Something that you might see in the race course or Seaworld aquarium show.

Right away I jump into Blender and draw 2 strokes of grease pencil.

I know that we can make interpolation between 2 curve strokes. My solution involves exactly this, I resample the curve strokes so that they have the same number of points, then make curves in between the 2 grease pencil strokes.

Then the next step, I am making a steppy patterns for the stairs. I make duplicates and then I simply loft the curves using UV Connection node.
