Session 2: 2D and 3D
What do we mean by three dimensional?
2D grid (X is short, Y has the long tail)
From 2D to 3D
The idea behind 3D printing and 3D modelling, is that you can break down a complex 3D object into 2D shapes. You can make 3D from 2D.
Look at your name boards. You were transforming 2D into 3D from the first minute you were in this room!

These Star Wars paper crafts show you how big, bold, blocky shapes on the page translate well into 3D.
2D shapes in real life
Sometimes, if you look closely, you can see that a three-dimensional thing is made up of two-dimensional things at different angles.
