The following pages will show and explain the grass-hopper definition created to obtain the adjustable joints

of Prototype 1 ‘Cellular Growth‘ as can be found in Part c.2. of sTuDIO aIR FINaL JOuRNaL.

76

aDJusTaBLE JOINT FOR PROTOyPE 1

create a hexagrid of size ‘x’ and explode it. Duplicate the lines

and points generated.

Evaluate the 3 intersecting lines and set the length of the joints’ arms as desired with a number

slider.

Place a frame at the ends of each arm line and deconstruct

the frame to obtain perpendicular bent lines on each arm.

1. explode hexagrid

2. create

arm lines

3. create

bent lines

77

Use evaluate curve with an ex-pression to ensure that the holes remain in the right position even

as the bent length varies.

Offset the arm and bent lines in both directions to give the joint

its widths.

Connect the end of the offset lines together and join them

to obtain the overall ‘triskelion’ form. Bake the form and trim

where necessary.

4. create joint

holes

5. offset lines

6. join & trim

78

WEEK 10

79

The following pages will show and explain the grass-hopper definition created to obtain the recursive

hexogon pattern of Prototype 2 ‘Cellular Expansion‘ as can be found in Part C.2. of STUDIO AIR FINAL

JOuRNaL.

80

REcuRsIVE hEXagON PaTTERN FOR PROTOyPE 2 aND FINaL DEsIgN

Use a polygon component to create a single hexagon with sides of ‘x’

length.

Create expressions for the distances in the ‘x’ and ‘y’ directions that the

scaled hexagons would eventually be moved to. (shown in red box below)

Repeatedly scale the hexagons by a factor of 0.5 and move them with the expressions created earlier. (shown

in green box below)

1. create

hexagon

2. determine

vector

3. scale &

move

81

Repeatedly scale the hexagons by a factor of 0.5 and move them with the expressions created earlier. (shown

in green box below)

Move down each of the scaled hexagons correspondingly by using a ‘negative’ component and the ‘y’

direction expression. (shown in blue box below)

Join all the hexagon cells together and bake the final product.

3. scale &

move

4. move

vertically

5. join full

structure

WEEK 11

83

The following pages will show and explain the grass-hopper definition created to obtain the overall final

design form as can be found in Part C.3. of STUDIO aIR FINaL JOuRNaL.

84

OVERaLL FINaL DEsIgN FORM

Bake overall 2D pattern of varying hexagion sizes using Grasshopper

Definition from Prototype 2. Selected cells are removed as desired.

Project the 2D pattern onto a curved surface. This enables the front of the

overall form to have an undulating face.

Create a duplicate of the curved pattern which is scaled smaller and moved towards the fishway on-site.

1. create 2d grid

2. project pattern

3. scale &

move

85

Create a duplicate of the curved pattern which is scaled smaller and moved towards the fishway on-site.

Loft both the curved 2D pattern and the smaller scaled pattern to obtain a

3D form.

Create a flat surface that represents the edge of Dights Falls to trim the

3D form, obtaining a slim overall form that has a straight-cut back.

3. scale &

move

4. loft

patterns

5. trim

excess
