You may get a better response to your question if you create a small worksheet just showing with a trimmed down example with all the not needed rouitines and variables omitted what your problem is and what you need.
You had posted the same question already before and I tried to open your sheet twice and every time my machine would hang and I had to close Mathcad via taskmanager - therefore I won't open it a third time.
From the description in the post its not clear to me what you are after. What is given ( a nested vector containing x,yz coordinates of points?) and what it searched for? Maybe you should give a small example where you manually type what output you would expect. But in every case - strip down your sheet or even better, create a new with manually typerd in small data which contains only the bare bones of what is necessary.
