OBJECT GIVEN: A Wooden Stegosaurus Model (Section and Profile System)
Method of Measurement:
Measurements for Drawing:
1. The model was photocopied and photographed. 2. The image was then rescaled to a scale of 1:2 in Photoshop using the basic measurements obtained earlier (bottom left of page). 3. The image was printed and traced over on a tracing paper.
Reason for Measurement method:
This measurement method was used due to the irregular nature of the many pieces in the model. Rescaling the photocopied and photographed model enable the process of drawing to be more accurate and efficient. It would have been time consuming and tedious to measure each piece on the model with a scale ruler and translate that into a good measured drawing.
NORTH (Stegosaurus’ head)
Basic Measurement Method: - The picture on the left shows how an upright ruler at a table edge was used to ensure that the ends of the model were measured from 0 mm. - The basic Length, Height and Width of the model was then measured and recorded.

- The shaded RED pieces indicate the main structural support system of the model. Without these pieces, the model would not be able to carry the pieces which are crucial to identifying the model as a stegosaurus.

Digital Modelling Process:
1. The board with pieces taken out were photocopied and placed in Rhino 5. 2. The pieces were traced with “curve” and “mirror” functions. 3. The traced pieces were “extruded” out as solids. 4. The solid pieces were then put into position by using “gumball”, “move”, “rotate” functions. 5. Once all the pieces were in place, A “wood material” was assigned to the pieces and the view was changed to “Rendered”. 6. Images of the rendered digital model were saved.

SKETCH MODEL IDEA:
I decided to challenge the rule of a Rigid Volume Appearance and create a FLEXIBLE Volume Appearance instead. Doing so incorporated the manipulation of ideas from how notched joint systems work. This enabled me to create a rotating joint that is usually not found in a rigid Section + Profile System.
SKETCH MODEL DEVELOPMENTAL PROCESS:
1. Pieces of paper were cut by trial and error to find the right measurements that would allow them to rotate smoothly when joined. 2. Once the measurements were known, the paper was used as a template to cut out the cardboard pieces as seen in the picture above. 3. The Cenral Piece was inspired by the 4 jointed piece found in the main support structure of the Stegosaurus model. In this model, it also acts as the main support piece for the 4 rotating side pieces. 4. Lastly, I initially cut gaps on 1 side of each piece. But, I realised that if gaps were cut on both ends (creating symmetrical pieces), the system could become more flexible, thus achieving a more Flexible Volume Appearance. MATERIALS AND EQUIPMENT USED

Although flexible qualities may be good, I realised that there may be a need for RIGID structures at times. Therefore, I then created another system to maintain the RIGIDITY of a chosen Profile after flexible shifting. This system is explained below: - 4 holes are pierced into the rotating piece (the piece with an arrow) as shown above. Satay sticks are put through the holes to hold the rotating piece in position. These satay sticks can be taken out to allow rotation of the piece once more and placed back into the hole when the desired position is attained.
An Alternative Sketch Model
Alternative SKETCH MODEL IDEA:
WIth the first sketch model done, I decided to experiment with a central piece that had angled joints instead. The result turned out to be quite good. However, the Volume in this profile could not be seen as clealrly. This idea could be further developed to create a better volume appearance by adding in more angled joints and side pieces. It has the potential to become an enclosing 2nd Skin that can be controlled by the wearer.
