Design Intention & Brief
In order to achieve simplicity and minimalist outcome for the stool design, the idea of vertical repetition structures used to create the form. Various variations (such as the density, thickness, shapes of structures) are tested out using a parametric system. The open area located in between MSD building and Union House (Melbourne University) is an ideal location to install the proposed stool. The open area is not only a pass by area but a place for students to hang out, having lunch with friends and discussions. Unfortunately, there are not many portable stools where students can shift around to their desired spot. The proposed stool is light in weight, allowing students to carry and move easily.

STEP 01:
STEP 03:
- Create a base point, move the points into three sections. -Add Vector XYZ to allow adjustments -Merged the six points
- Using ArcPolar command, to repeat the structure in circular order.
Top outer ring New Center Point Point C1 Radius of the outer ring
STEP 02: - Connect all the points using PLine -Extrude the PLine, by inserting Sweep1 after adding PFrame and Circle commands
STEP 04: - Linked the C1 point to a new center point using Deconstruct commands, extrude the ring using Pipe command - Add distance command to allow update on diameter of the ring when Point C is change

1. Insert the first point (parameter) command in GH, the first point (Point A) is the base point.
Design Workflow
2. Insert Move command (component). Connect the output of Point A to the input of Move component.
Initial Sketches (refer to pg 3)
Lines & Point in Rhino
Data Matching in Grasshopper (GH)
3. Insert Vector XYZ command (component). Connect the output of Vector XYZ to the input of Move component.
1. Draw basic outline/profile of the stool by creating six points in Rhino with correct width and height.
Photoshop & Indesign
Export from Rhino to PDF
4. Add number sliders to the input of the Vector XYZ, to allow the adjustments of the points.
Bake to Rhino
1. Export the grasshopper model into Rhino by using the Bake command.
5. All points are Merged and connected to PLine. After PLine, the structure of the model begins to extrude using circle linked to the output of PFrame (to position the starting point of extrusion), then Sweep1. Arrpolar is used to array the single extrusion. (Repetition) 5

Matrix Variations A. Density The amount of strucutres give out different density, the more dense, the better stability.
B. Rectangular Structure The denser the structure, the heavier it looks & required more materials.
C. Circular Structure The denser the structure, the heavier it looks & required more materials.
D. Converged Structure The amount of structures joint together.
E. Center Twist Tilting the center of the stool, to create a rotating motion effects. 6

A2 Pro
B5 : The structure is thin and light, better mobility for users to shift the seating. : Cheaper to construct. (Minimal materials use)
Cons : Flimsy structure that barely support external load (human weight).
Pro
E2 : Compact structure forms better stability that allows to support external weight.
Cons : Expensive to construct. (Greater amount of ma -terial use) : Bulky and heavy to carried.
Pro
: Unique form of twisting structure. : Thin and light structure provide better mobility for users to shift the seating. : Cheaper to construct.
Cons : Flimsy structure that barely support external load (human weight). : Bulky and heavy to carried. 7

Design Process
Design Process 01
Design Process 03
Using the minimal form of Variation A2, twisting Point B1, by adjusting number slider at X-axis from 0 to 100.
Decreasing the Y-axis for B point from 150 to 80 to narrow the top centre ring, to ensure a better siting platform.
Design Process 02
Design Process 04
Increasing the structure componets by adjusting the count for Arcpolar. The radius of sweeped circle remind unchanged to ensure the lightness of form.
To link the top outer ring and the edge point of the structure, Deconstruct commands are added to join the Point C1and base point, the outer ring will update according to the changes of the width of structure.

Exploded Isometric
Outer Ring -400mm diameter with 25mm thick circular metal strips -Black Powder Coating finish as decorative and protective layer. - The outer ring is welded to every edges of the structure. - Act as support member that holds the structures in place.
Single structure -~830mm with 25mm thick circular metal strips .-Tilted 100mm in X coordinant.
Center Base - The structures are welded together in circular direction.
Single structure - Tilted 30°
