modelling and testing

Question 1

what does modelling allow?

Answer 1

-allows you to see the product in 3D
-allows the client to test out the product
-allows you to see details of functionality and construction more clearly
-see proportions and sizes clearly

Question 2

what materials are mostly used for modelling and why?

Answer 2

calico- it’s cheap and very basic

Question 3

why is evidence of development crucial?

Answer 3

it demonstrates the ability to refine, evaluate and test out an idea

Question 4

what is a virtual model?

Answer 4

a model produced using CAD software to understand the product without actually making it

Question 5

what is a toile?

Answer 5

a full size mock-up of a product

Question 6

what should you test in a product?

Answer 6

-ergonomics of a product to make sure it suits the user
-materials and construction methods to ensure success
-surface finishes can be sampled and tested for suitability

Question 7

what three other things will you need to do along with testing?

Answer 7

-evaluate results
-carry out improvement
-refine your design

Question 8

what could you use to help you with testing?

Answer 8

your design specification- you can use it as a checklist and can help you evaluate your project progress

you can also use summative evaluation- compare your prototype to similar products on the market

Question 9

what are some examples of iterative design?

Answer 9

1. testing and evaluating models
2. getting regular feedback from clients
   3.making lots of models
3. using CAD to show a range of solutions

Question 10

what is iterative design?

Answer 10

making small changes and developing throughout the design and modelling stages
