Modelling Flashcards
Why are models used?
In design, models are used for a variety of different purposes, including:
Generating and explore ideas
Developing and refining ideas
Test and refine ideas
Visualising an idea in 3D
Evaluating and testing ideas and
design issues
Communicating ideas
Solving ergonomic, functional and
aesthetic problems
What are the advantages of using models?
Used to communicate complex 3D forms
Can be shown to others for feedback
Can be used for testing
Some CAD models are very accurate and can be easily shared electronically
What are sketch models?
Sketch models are models made quickly from cheap, readily available materials to allow designers to create their initial ideas in 3D.
Why are sketch models used?
They can help designers visualise their ideas more clearly than they could with a sketch, to develop their initial ideas and to check aesthetic elements of their initial designs.
When are scale models used?
These are created when building full scale models is impractical.
Models are created on a smaller, or sometimes larger, scale but all proportions are kept the same.
Why are scale models used?
This allows the designer to see their ideas in a physical form, check appropriate sizes and proportions of parts and to clearly communicate their ideas to their client.
What are block models?
Block models look exactly like the final design on the outside but have no working or moving parts.
Why are block models used?
These can be used to test ergonomics, aesthetics and for advertising purposes.
Summarise what a cad model is
CAD models are produced using computer aided design packages and are very realistic and accurate. Changes can be made quickly and easily.
Why are CAD models used?
They can be tested in a virtual environment, used with computer aided manufacture and also be used for marketing and promotion.
What is a prototype?
A prototype is an early model or release of a product built to test a concept or process.
The prototype is made to be as close as possible to the final design, using the same manufacturing methods that would be used for the final product.
Why are prototypes used?
enables full scale performance testing
allows the designer to identify any last minute problems with the product.
provides clients with a fully working product.
