IB Design Technology Topic B2.2: Modelling and Prototyping Key Definitions

A structured list of all components, parts, and materials, often including quantities, part numbers, and descriptions.

CAD (Computer Aided Design) refers to the use of computer software to create, modify, and communicate design ideas with precision.

A computerised simulation method that breaks down a model into small elements to analyse how it responds to physical forces.

A tangible, real-world model of a product, built using physical materials.

Rapid prototyping is the use of 3D printing and other additive techniques to quickly create physical models from CAD designs, allowing fast testing and feedback.

Digital 3D models that provide a complete representation of an object, including its external form, internal structure, and material properties.

Digital 3D models that represent only the external surfaces of an object, without defining its internal structure or volume.

The degree to which a product enables specified users to achieve defined goals effectively, efficiently, and with consistency and predictability.

Digital representations of a product that go beyond physical form to include simulations, animations, and interactive elements for testing and visualisation.
