1. Year 7 Graphics – Orthographic Projection
Objective:
To understand how to produce an Orthographic Projection drawing
Outcome:
To be able to use orientation or views to communicate and represent our design ideas.
Starter
Look at this object.
At what point did you realise it had a hole through the middle?
How could you possibly show each view if drawing it 2D?

1st
Draw the FRONT view
2nd
Then to the right draw the SIDE view

Task 1:
Can you correctly label the following views with the correct letter?

Yellow
Task 2:
Using what you have learnt, you are now going to draw the 3D wooden cube in front of you 2D using orthographic projection on the template . With a scale 1:1. You will need a ruler.
What does scale and what does 1:1 mean? How would you make it look wooden? Where is the light source in this picture? Can you fill in this table?

Task 3:
Using the other wooden block that is in a shape of a step/ block with hole to produce an orthographic drawing using the template.

7. Year 7 Graphics - Orthographic
Plenary:
How would you do it? 5-5-1
A new student has joined the school and you have to explain what orthographic projection is in 5 sentences.
Then do the same for the process.
Could you then summarise it on 5 words then 1 word.
