#learn grasshopper

In this Grasshopper tutorial for Beginners, we will learn about the Closest Point component. This component expects two collections of points, and it will go through the first collection one point at a time, measure its distance with all the points in the second collection, and place a point on the point with the shortest distance. It will also output the distance values. We will see how to use the distance values to create interesting shapes. We'll keep this tutorial very simple.

In this tutorial, we will learn about the Prune Tree component. This component will let you take a tree(a list of sub-lists), where the number of elements in these sub-lists (or Branches if you like) is not the same, and then, using the Prune Tree component, you can grab only the sub-lists with a predefined minimum and maximum number of elements, and exclude the others.
