Design and Technology KS3/4: Why is CAD/CAM essential in design?

CAD/CAM is a highly cost effective design tool used by the Royal Navy.

Take a 'virtual' tour as a design engineer aboard HMS Astute.

A Computer simulation is used to try out and test real life issues.

Potential problems are reviewed and changes can be made.

At this stage of the design process CAD/CAM saves the Royal Navy time and money.

Teacher Notes

Could be used to show how Computer Aided Design (CAD) software can be used to simulate the performance of materials and structures without the need for expensive physical testing models or prototypes.

The clip might be used alongside a unit or work focusing on 3D, or 'parametric', CAD software and 'Finite Element Analysis' (FEA) functions, for testing the materials and structure of drawings.

In addition to the practical application of CAD in design and testing, the clip might be used to provide information, advice and guidance on careers in naval architecture and design engineering.

Curriculum Notes

This clip will be relevant for teaching Design Technology.
