### Scale Nu

In this grasshopper tutorial I will talk about the Scale NU tool and how you can use it to scale a set of rectangles non uniformly. First we will array a square and then define a rotated plane to scale the squares diagonally. We will use point attractors to define the weight of scale.

### Voronoi Cell

In this Grasshopper tutorial, I will talk about the Voronoi cell component and how you can combine it with weaverbird to produce smooth mesh. First, we will talk about the center point and the neighbors and then by defining the bounding box, you can produce the Voronoi cell.

### Tree column structure

In this grasshopper tutorial, I will use the closest points tool to produce a tree-like structure. first of all, I will make a freeform surface and divide it into panels and then we will produce parametric points for the location of the columns.

- 6th May 2018
### Random

In this video tutorial, I will show how you can use “random” to produce random numbers and use them in your modeling. We will use random numbers for extruding a set of panels in their normal direction and learn how to change the random numbers.
