IDEATION AND DESIGN

Recipe of analytical drawing: 1) Find a shape to be cracked, like a 10cm square. 2) Find the centroid of the square and midpoints of the four perpendicular sides. 3) Draw lines (L8) to connect centroid with four midpoints and four 90- degree angles as well. 4) Draw a straight line inward to outward between each lines (L8) that did in step 3 which must be in a certain interval scale. 5) Repeat step 4 until the lines meet the 90- degree angles.

This picture considers as a broken glass which contains spiral and cracking (Aranda & Lasch 2006). It broke into regular patterns which consist of circle and rectangle around the centre point that shows the movement of the item.

IDEATION AND DESIGN

ì  I have created several models to show the different forms of the model. The first set of patterns which is based on the recipe for a broken glass which represents the idea of symmetry and balance.

This set of patterns which change the shapes by discarding the surrounding of octagon and stretching the eight diagonal lines to achieve the effect extending and penetrating.

IDEATION AND DESIGN

The outcome of the analytical drawing is an octagon, and I was trying to decompose it to create another form of model. I just simply cut down the clay along the four diagonal lines and result in 8 small pieces of clay. Pinch the small elements in a regular method, side to side and angle to angle and finally form the strip which is similar to bone. However, it is quite boring for just only one singe strip, so I made three different length of strips, connect each both ends and displaying as the bigger circle incorporate the smaller one.

Followed the third method in Appendix, I started to create the contours by cutting and tracing sectional slices. Firstly, place the model on a paper which has 5mm intervals parallel lines. Then cut the model into slices as parallel as possible. Finally lay the slices on a paper that has gird and trace the first slice.

IDEATION AND DESIGN

ì  Import the drawings into rhino and follow the instruction on the video. After lofting, it finally come with the form below. It seems not very similar to the one in video due to the distribution of the curves. Additionally, the shape looks not that smooth also because the curve is not straight. The one on the right is another version which is more straight and taller than the left one.

IDEATION AND DESIGN

ì  I constructed four kinds of 2D paneling by using rhino 2D grid which are BOX, BOXX, DIAMOND and TRIBASIC. Also about the cavity of each of them. I constructed two kinds of 3D paneling by using rhino 3D grid which are PARTITION and PIRAMID.

FINAL VERSION OF MODEL- PROCESS

Firstly, I decided to use the panel custom 3D to make the model. I attempted to make an octagon because it is the basic element of my natural pattern. However, I found it was not well connected to each other when making a panel custom.

Then I thought hexagon can be an alternative one. Then I tried to make a hexagon panel custom and it seems well connected to each other.

During the process of making, some problem encountered. I have tried several not too effective methods, like this one. I need to delete the curves to meet the hexagon and it took me for a long time.

FINAL VERSION OF MODEL- PROCESS

Finally, I found the Library 3D is the best choice to make the model as it is the most effective to do the panel custom 3D. After the Library, the model will just look like the left one, and the right one is after running the the Fin edges in paneling tools. The two models below is after optimising in the view of shaded and rendered.

     

UNFORD MODEL

Following the videos, the model can be unfolded into a set of flat shapes. After this step can use the command textobjects to label the the shapes.

Use the grasshopper to make the dashed line. There is always some problems when prepared for unrolling, such as, the polyline. Also some problems that happened during the unrolling. For example, the overlap or it cannot join together.

  UNFOLDED CUTTING TEMPLATE  

   TOOLS FOR PRINTING AND CUTTING

 DESIGN OPTIMISING AND MATERIAL USAGE

In my situation, the card thickness is quite because it decides the model can stand up or not. IT must be a thick cardboard, then the geometry would not fall down. PROBLEMS IN THE PRINTOUT: Firstly, I used scalper to cut the shapes that printed in the card because the knife of the machine is not sharp enough, the curves cannot torn easily. But then I found out the scalper is not the best choice to use in cutting the curves, it looks rough. Thus, I changed it into scissor, and the shapes can be cut smoothly. My model is quite different because it does not need tab and the way it unrolling is special too. It cannot unroll for a whole layer but one strip in a layer each time. It divides into 51 thin strips and the unit is small, so it is really hard to connect well even use the cardboard.

BUILDING PROCESS OF THE FINAL MODEL

After the cutting by the cut cutter. I cut the shapes along the curves that were scored. Finally 51 stripes were cut and then folded each strip along the dashed line, After that glue each two strips together to from a group of hexagons. Finally, just glue all the layers together to form the final model.

Then, I redid the model by hand, cut down two squares (5 cm) and four rectangles (5X7cm) with tabs, then glue them to form the hexagon. Repeat this step and finally can form the revised model.

 

FINAL VERSION OF MODEL- PROCESS

After I found out the problem of my model that the unit of previous version is too small which is about 1cm, thus I change the pattern with the panelling library and finally built the very final version of my model.

From the previous page show that I found out is difficult to from the model, then I just tried another way to build the model. Below is the process that I made the model by hand.
