1. Year 7 Graphics – Isometric Drawing
Objective:
To understand how to produce an isometric drawing
Outcome:
To be able to use angles and views to communicate and represent our design ideas.
Starter
Look at these 2 cubes.
Are they both 3D? Why is it 3D?
What is different about them?

2. Year 7 Graphics – Isometric Drawing
Isometric Drawing is a way of showing a three-dimensional (3D) in two-dimension (2D) on an angle of 30° on the horizontal.
30°
Isometric grid paper can be used to help draw in isometric

3. Year 7 Graphics – Isometric Drawing
Process:
1st
Draw the vertical line in the middle.
2nd
Then draw the parallel lines at 30° angle of the vertical line.
3rd
Draw the vertical lines joining the parallel lines.
4th
Draw the other parallel lines in the correct distance apart
5th
Add the remaining lines
3D Object

4. Year 7 Graphics – Isometric Drawing
Isometric Paper
Helps you draw objects in isometric.
Each triangle or dot is angled to be 30° and at a 10 mm spacing.
If you are drawing at scale 1:1 what does this mean?

5. Year 7 Graphics – Isometric Drawing
Task 1:
On the dotted isometric paper draw:
A cube H10mm x L10mm x D10mm
A cube H20mm x L20mm xD20mm
A cuboid H10mm x L20mm xD10mm
A cuboid H20mm x L10mm xD10mm H L D

6. Year 7 Graphics – Isometric Drawing
Task 2:
Using what you have learnt, you are now going to draw a cube to scale 1:1
What does scale and what does 1:1 mean? How would you make it look wooden? Where is the light source in this picture?
Add:
Surface texture
Colour
Light source
Shadow
Shaded side
