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 2 D?

Year 7 Graphics – Orthographic Projection is a way of showing a three-dimensional (3 D) in two -dimension (2 D) Plan/ Top Front Side

Year 7 Graphics – Orthographic Projection Task 1: Can you correctly label the following views with the correct letter?

Year 7 Graphics – Orthographic Projection FRONT SIDE TOP/PLAN Task 2: Blue Using what you have learnt, you are now going to draw the 3 D wooden cube Redof you 2 D using orthographic projection on the template. With a in front scale Yellow 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?

Year 7 Graphics – Orthographic Projection 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.

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.
