algorithmic modeling for Rhino
Hi, I am new to grasshopper, I am trying to analyze a surface by its angle variation.
I only need three outputs:
The area lower than 20 degrees
The area between 20 and 40 degrees, and
The area above 40 degrees
I found a program already made but it only analyzes Mean or Gaussian surfaces (I added the file), and I have no idea how to change this paramater into specific angle variations.
The purpose of this is to find the exact limit of a topography where the terrain's slope turns sharper, which to our government are the angles I express before.
I would appreciate your help,

It worked in a tiny surface, like the one you tested it. But I turn all red when I applied it to the terrain I'm analyzing (check attachment).
Thank you!

I suppose you'd be better off flipping your terrain surface normal direction.
hahahahaha, I already tried that. Well, I flipped it in various direction. I do not know what normal direction would be, sorry.
This is the file
Genius! thank you very much!
I don't want to take any more time from you, this is the last thing, what tools would you recommend me to draw the border of the areas with a line? So when I bake it, I can do a make2d in order to transfer this information into a blueprint
I'm sorry for the bother, and thank you very much!
