Lesson 4: 3D CAD models

Learning about the applications of 3D modelling and printing in industry such as film and animation. Developing existing essential 3D CAD skills to combine 3D objects to form a complete product in CAD 3D modelling software.

Learning objective

  • To develop 3D CAD skills to produce a virtual model

National curriculum


Pupils should be taught to:

  • Generate, develop, model and communicate their ideas through discussion, annotated sketches, cross-sectional and exploded diagrams, prototypes, pattern pieces and computer-aided design



Pupils should be taught to:

  • Evaluate their ideas and products against their own design criteria and consider the views of others to improve their work

Main event


Pupils needing extra support: Go through the Pupil video: Tinkercad 3D modelling and pause it after each stage for the pupils to copy. Provide pupils with the ‘The Tinkercad remix project’. Instead of creating a project from scratch, they can pull the remix project (slide 10) apart in Tinkercad, or, revisit the Tinkercad remix project from Year 5: Digital world: Monitoring devices’ for the children to pull apart and rebuild.


Pupils working at greater depth: Can be challenged to continue developing their Tinkercad skills to combine multiple objects to add extra features and functions directly on their 3D model in Tinkercad.
