| For the second design, I wanted to create a stand alone weave structure. Having no experience in Grasshopper, I needed to use a tutorial ([[http://www.grasshopper3d.com/video/defining-a-parametric-weave|http://www.grasshopper3d.com/video/defining-a-parametric-weave]]) to create a weave.

| - | + | * Create a Cull Pattern (Sets tab, Sequence), with boolean toggle values (Params tab, Special) as input i.e. true or false, and link to a tree Branch (Sets tab, Tree) - in order to isolate different points to then manipulate separately (to create the up and down directions for a weave) | |

| - | + | * Use Vector Amplitude (Vector tab, Vector) with a number slider - to specify the height of points | |
| - | Move a row of points up | + | * Use Flip Matrix (Sets tab, Tree) - to flip rows and columns to change the direction of the points (from y direction to x direction) |
| + | * Use Weave function (Sets tab, List) - to weave between 2 points, and using a boolean toggle to change the weaving pattern | ||
| + | * Use Interpolate Curve (Curve tab, Spline) and the weave function as the input - to create curved lines between points | ||
| + | * Cull again to isolate curves, i.e. the middle curve or the outer curves (of 3 curves) | ||
| + | * Use Rotate 3D (Transform tab, Euclidean) - to rotate outer curves | ||
| + | * Copy steps and switch true / false values - to create curves that are inverted/opposite to the original curves that form the basis for the up and down weave structure | ||
| + | * Use Pipe Component (Surface tab, Freeform) - to change lines (of the curves) into pipes, with a number slider to change thickness | ||

| and I adapted it slightly to experiment with a new design. The change I made to the original design was to mirror the design on top of itself - to create 2 layers of the weave structure. Printing this double structure with flexible filament, I was interested to see the results, how it would feel and what it would be like when pressed together. | and I adapted it slightly to experiment with a new design.

| It was useful to experience Grasshopper, however I found the program difficult use. It was hard to me to find the right function that I needed for a design element I had in mind, and to know what input the components required; often, the program produced results I didn't expect. I am aware that my first design is very simple, as I found it difficult to produce a more complicated structure that I wanted. | It was useful to experience Grasshopper, however I found the program difficult use.
