Introduction to 3D modelling
I can recognise that you can work in three dimensions on a computer.
Lesson details
Key learning points
- Computers can be used to model real-life 3D items.
- 3D models can help the design process and enable people to view parts of objects in detail.
Keywords
2D - two dimensional - 2D shapes are flat and have no depth
3D - three dimensional - 3D shapes have height, width, and depth
Perspective - the position from which you see an object
Common misconception
Computers are only used to make imaginary models that can’t be created in real life.
Architects who design real buildings use 3D modelling software to ensure their designs are accurate.
You will also need to be familiar with creating, selecting, and moving 3D objects within Tinkercad, including how to view them from different perspectives. Tinkercad�s Start Learning 3D tutorials provide a good starting point: oak.link/tinkercad-tutorial.
Teacher tip
Equipment
Pupils will need access to a device with 3D design software. Examples in this lesson use Tinkercad https://oak.link/tinkercad
