Array of oriented 2 points boxes from a linear array

Hi everyone, 

I would like to generate an array of oriented 2 points boxes from a linear array. 
What I have managed so far is to manually produce some of the boxes as you can see on the attached screenshot. 
Instead of manually generating each of the boxes, I would like to generate all of them at once using two lists of points. I have identified what are the two lists of points I would need to generate, but I am not quite sure how to do this? I thought about path mapper, but I could not manage to make it work as I would like. So maybe you could help me :)

The two lists of points (one for each corner of the 2 points boxes) would be in terms of {branch path}(index) :
1. {A;B}(i)
    {A;B}(i+1)
    {A;B}(i+2)

2. {A+1;B+1}(i+1)

    {A+1;B+1}(i+2)
    {A+1;B+1}(i+3)

I hope this is clear enough.

Cheers
