For this summative task, we will:
*Drawings need to be turned in by the due date.
Use the terminology in the diagram below in order to communicate your ideas clearly.
For this strand, you will note which bridge design you have chosen and develop an orthographic view. Give examples for how your chosen idea fits the requirements outlined in your Design Specification.
An orthographic projection of your final bridge design shows the top, side, and end views of your bridge. This will better communicate the bridge design and allow you to see any mistakes before developing the final design.
Below is an orthographic projection of a stone staircase. It is visible from the top, three-quarter view, side and bottom.
Below is another example of a house.
An isometric projection shows a 3D view of a design, but it is not in true perspective. Note the house above. The design is drawn on graph paper with 30 degree angles.
An orthographic/Isometric worksheet will be handed out in class.
Develop a side view of your final design in 1:1 scale. Annotations which describe how the materials will be used will better communicate your idea. Use the terminology listed above when annotating your design.
*The final design will be on A3 paper which I will hand out to the class.
It can be helpful to trace your popsicle sticks when drawing a side view of your final design. This will ensure that it’s 1:1 scale. Each popsicle stick is 115 x 10 x 2 mm.
The example below shows one of the completed bridge sides.
Your final design will be shared with the group and discussed. The group shall choose the design that is has the best chance of success and follows the design specification closely. It’s therefor important to have a complete and well annotated design in order to communicate your idea to the group.
