Problem with project. Ways to avoid a loop

Hi!

I have to create a structure based on angles from the points of collision. It's very easy to do with grasshopper but my code looks very dump. Is there a way to do this process without repeat the same command one time, and other, and other...? 

At last the problem is that i new the new point to generate the next, but i understand that it should exist a better way to do it. Something more effective.

Could someone help me? thanks!
