Iterate with CAD: saving space
Lesson details
Learning outcome
I can iterate ideas for the context 'student living' using 3D CAD.
Key learning points
- CAD is part of the iterative process and is used to develop your idea by viewing it virtually and analysing the idea.
- Sketching over your CAD drawings can help to develop the idea before going back to make those improvements in CAD.
- Before developing your ideas in CAD your sketches should be evaluated.
Keywords
CAD - computer-aided design
Development - improving and building on design ideas to make them better
Iterate - process of refining and improving a design
Common misconception
Modelling using CAD is the final step in the development of designs.
CAD is part of the iterative process. CAD should be used as a way to develop your idea by viewing it virtually and analysing the idea. Sketching over your CAD drawings can help to develop the idea before going back to make those improvements in CAD.
Teacher tip
You may need to print out students CAD designs in advance of this lesson to help with the flow and productivity.

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.
