Modifying 3D objects
Lesson details
Learning outcome
I can identify that digital 3D objects can be modified.
Key learning points
- When a shape is selected, a number of ‘handles’ appear.
- The white corner handles will resize the objects in two dimensions, changing its width and length.
- The black handles on each side of the base of the shape will resize the shape in one dimension, either width or length.
- The black cone shaped handle on top of a shape enables you to lift or lower a shape relative to the workplane.
Keywords
Handle - a shape that indicates when an object is selected, and that can be used to move and resize an object
Resize - to change the size
Recolour - to change the colour
Common misconception
The shape inspector is only used to change the length or width of a shape.
You can use the shape inspector to customise different properties of a shape, including recolouring shapes.
Teacher tip
You will need to be familiar with resizing, lifting/lowering, and altering the colour of 3D objects in Tinkercad.
Equipment
Pupils will need access to a device with 3D design software. Examples in this lesson use Tinkercad https://oak.link/tinkercad

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.
