Exploded diagrams in CAD
Lesson details
Learning outcome
I can use Tinkercad to draw exploded diagrams.
Key learning points
- Exploded diagrams show how the separate parts fit together to be assembled.
- Each individual piece of a design needs to be drawn separately in an exploded diagram.
- Tinkercad has a notes tool that allows designers to make annotations.
- Tinkercad orthographic view shows designs to scale from the front, back, top, bottom and side views.
- Tinkercad orthographic view shows designs in isometric with shape sides drawn at 30 degree angles from the horizontal.
Keywords
Exploded digram - a drawing showing how separate components fit together
Perspective view - viewing 3D objects in 2D, where objects look smaller as they get further away
Orthographic view - viewing 3D objects in 2D to scale, showing each side of a design without perspective
Isometric - drawing 3D objects to scale, with shape sides drawn at 30 degree angles from the horizontal
Annotate - add notes or labels to something to help explain it
Common misconception
Exploded diagrams have to be in perspective view.
Orthographic view is a better viewpoint for seeing the exploded parts of the eco-house.
Teacher tip
Pupils may wish to use previously saved work but if they are really complex designs then the pupils may wish to start a new design.
Equipment
Access to Tinkercad on tablet, chromebook or laptop.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
