from your definition it's hard to get a sense of what you're trying to achieve.  For one thing, all of your list items are set to select the fifth index value from each curve.  How are you trying to connect the triangles exactly?

if that helps I am trying to create something like this:

The trick in the attached lies in the relative items components.  the general logic is this:  you build a rail curve, divide it into frames, rotate the frames incrementally, and apply polygons to the frames.  I've added a graph mapper in there to dynamically adjust the radii of the polygons...you could do this really any way you like.  Then you split the polygons at their kinks to get your initial points.  This places them into a very useful data structure for organizing your polylines, with points for each polygon contained in a distinct path.

The "relative item" component may be hard to grasp at first, but think of it like a double-shift of sorts.  The FIRST shift goes into the {n} format of data paths, and the SECOND shift goes into the (n) format of the items in each path.  By playing with these values you can select sequences of points along the polygons that will triangulate in a variety of ways.  I'm not sure if the way I've done matches the strategy in your image, but hopefully it can get you started on a series of explorations.  The logic makes for some fun playing.  Good luck!
