WEEK 6 READING: SURFACES THAT CAN BE BUILT FROM PAPER IN ARCHITECTURAL GEOMETRY

PANELLING 2D PATTERN

Question 1: What are the three elementary types of developable surfaces? Provide a brief description.

(Maximum 100 words)

They are cylinders, cones and tagent sufaces of sapce curves. They are all ruled special surfce since a tangent plane is always tangent to the surface along an entire ruiling and not just in a single point. The Gaussian spherical image of these surfaces is a curve because all points of the same ruiling have the same tagent plane. As a result, they have vanishing Gaussian curvature and can therefore be unfolded to the plane without distortion. Many developable srfaces are compsitions of such developable ruled surfces.

2d Panelling, Pattern: Triangular

Question 2: Why is the understanding of developable surface critical in the understanding of architectural geometry? Choose one precedent from Research/Precedents tab on LMS as an example for your discussion. (Maximum 100 words)

Because developable surfaces are applied in many desings of comtemporary architectures and constructions nowadays. The developable surfaces have many properties that are attractivefor architectures, for example, the connection of a surface by a union of developable strips. The design of the Puppet Theatre in Harvard, which looks like a shelter, prodeuced from the developable surfaces to create a complex architecture surface. The surface is interlocked by pieces of triangles panels to creat a diamond shapes and rigid structure.

VARIABLE 2D PATTERN

3D PANEL TEST PROTOTYPE & TEMPLATE

I firstly use the circle tool to creat a circle outline as my 2D pattern, then I creat a closed curve on the base surface by using the panel 2D custom variable. I also use the box pattern to make another 2D panel. The third step is to put the command “projecttoCplane� and use the spilt tool to combine the two panels together and turn the closed curve into a grouped open surface.

For this 2D panelling, I creat a face by using the polyline and circle tool and use the same way as the first panel.

I creat some geometry shape in one bounding box and use the same way as the first panel. The difference is that for this panle I chose the original base suface as the object to split to creat the holes on the suface.

These are my testing unroll templet. I firstly creat a 3D panels on the base surface by using the panel 3D custom variable and I join 3 or 4 of them in one group. Next, I unroll them and creat the taps for adhesion of the whole model. It is imporatnt to triangulate the obejects before creat the 3D panel. This is because the surface of the object will not be flat on the 3D model, which may make the unroll templet overlaped or disconnected.

From the process of the folding the test unrolled template, I find that it is very useful to make a scratch on the folidng line as the scratch makes it easy to fold and also show the clear lines on the surface.

WEEK 7 READING: DIGITAL FABRICATION

EXPLORING 3D PANELLING

Question 1: What is digital fabrication and how does it change the understanding of two dimensional representation? (Maximum 100 words)

Digital fabrication is a design process by using the 3D modeling software or computer-aided design and manufacturing (CAD/CAM). There are some common forms of digital fabrication such as punching, laser cutting and CNC routing. It not only makes two-dimensional drawing more efficient and convinient, but also takes three-dimensional modelling to energize design thinking and expand the boundaries of architectural form and construction.

Question 2: Suggest two reasons why folding is used extensively in the formal expression of building design? (Maximum 100 words)

The first reason is because folding is a gerneratiive design tool which can not only creat fluidity and multifuctionality with continuous surface, but also expands the three-dimentional vocabulary of surface by naturally producing deformation and inflection. Alos, folding provides a great variety because it is inherently capable for manifesting a wide range of forms. It can turn two-dimensional surfaces into modulated three- dimensional spatial construct.

For this 3D digital model, I firslty creat the panelling grid (10*10) on the base surface and the offset points (mini distance:10; max distance: 59.4) over the surface. Then I make three single modules in different shapes as my 3D patterns. I use the panel 3D custom variable creating the whole model where the heights of the objects rise gradually from the edge to the centre.

The whole module which is combined by the 3D panel and 2D panle. I set wave pattern in the 2D panel by using the 2D grid in Rhino. By comparing the digital module and the paper module, I find that the underside of the physical module is not so accidented as the digital module. I use the top line and the bottom line (picture 1) as my curve attractor, which create a variation of heights of each object. The heights of them are attracting to the middle from the sides.

While unrolling the panles, I try to join 2 to 4 objects in one group because it is a easy way to unroll the whole module. In the process of folding the module, I learn that it is good to use the pen knife to make scratch on the folding lines, since it not only make it leasy to fold but also make the model more clean and tidy.

While unrolling the panles, I try to join 2 to 4 objects in one group because it is a easy way to unroll the whole module. Then I creat the tabs (distance: 5; recess: 5) for the adhesion of the module. It is also important to mirror each templet to make the folding lines on the underside. After finishing the unrollin step, I put all of the templets into one A0 size box and export them into illustrator to change the line weight.

PANELISED LANDSCAPE

APPENDIX

This is the underside of the model, where I stick each group of panels together by applying the glue on their tabs.

Material used: pen knife, mental ruler, glue, cutting mat, 160gsm mat paper.-

These are the pictures of the details of the panles. In thhis module, there is a big variation on the heights of each objects so that we can see a wave from the elevation. Also, the variation of the topography of my terrain create an effect which the top of the 3D panles have a flling slop from the middle to each side.

This is the contoured base surface for the whole module. I set the paneling grid (10*10) on the surface and the offset points (mini distance:10; max distance:59.4) over it. The image on the rhight hand side shows the three seperate modules for the 3D panellig. For these objetcs, I use the “triangulatemesh� to make their surfaces flat so as not to get the overlaped or seperated unroll templets
