The 20 questions

  1. What is a 3-D model used for in design?

    • To record the full name of each person who worked in the team on the project
    • To calculate the profit that the product will make once it is on sale
    • To show the designer's personal style and taste to the teacher in class
    • To test the shape and fit of an idea before making the real product

  2. Which material is commonly used for quick low-cost card models?

    • Fine porcelain with a glazed finish
    • Solid cast iron with a machined surface
    • Tempered glass with a polished edge
    • Corrugated card or foam board

  3. What does a mock-up show?

    • The cost of making a product in a factory
    • How a product works in full, with working electronics
    • The final product as it would be sold in shops
    • How a product looks and fits, but not how it works

  4. Why is a prototype different from a mock-up?

    • A prototype is shown only to customers after the sale
    • A prototype is only ever drawn on a computer screen
    • A prototype is built to test how the product works
    • A prototype is always made from gold or silver

  5. A designer uses a computer to model a box and check its volume. Which area of modelling is this?

    • Mathematical modelling
    • Oral presentation of the box's features
    • Hand-drawn colour rendering of the box
    • Photographic recording of the box's surface

  6. What is the volume of a box that is 10 cm long, 5 cm wide and 4 cm high?

    • 19 cm cubed
    • 200 cm cubed
    • 400 cm cubed
    • 50 cm cubed

  7. A box is 8 cm by 3 cm by 2 cm. What is its volume?

    • 13 cm cubed
    • 24 cm cubed
    • 48 cm cubed
    • 96 cm cubed

  8. Why build a model at a scale such as 1:10?

    • It makes the model exactly the same size as the product in every way
    • It shows that the product is ten times harder to make in the workshop
    • It allows a large product to be modelled in a manageable size
    • It means the model can be sold for ten times the price of the real product

  9. What does a working model show that a mock-up does not?

    • How much the product would cost to package
    • How the moving parts function together
    • How the product would look in a shop window
    • How the product's name should be printed on it

  10. Which is a benefit of testing a 3-D model with users?

    • It guarantees that the product will be the cheapest item on sale in all shops
    • It removes the need for any written design specification for the whole project
    • It means the product never needs changing at all once testing is complete
    • Their feedback can show problems before expensive manufacture starts

  11. Which tool is often used to make accurate card or plastic models?

    • A craft knife with a metal ruler
    • A large hammer and a pile of rough nails
    • A welding torch used on thick steel plates
    • A pneumatic riveter used on sheet metal

  12. What does modelling let a designer check about a product's size?

    • The exact colour of the product in daylight when it is on display
    • The name of the factory that will produce the product for the whole range
    • The number of people who would buy the product in the first year
    • Whether it fits the space or user it is intended for

  13. A designer models a handle and finds it is too small for an adult hand. What should happen next?

    • Revise the handle size and build a new model to test it
    • Ignore the problem and go straight to final manufacture
    • Remove the handle entirely from the design
    • Make the handle smaller still to save material

  14. Which statement about 3-D modelling is most accurate?

    • A model always replaces the need for any kind of testing of the finished product
    • A model is only needed when the whole product has been finished and is ready
    • A model can reveal problems in shape and fit before real materials are used
    • A model must always be made in exactly the same material as the final product

  15. What is a template in modelling?

    • A printed booklet explaining the design brief to the students in class
    • A pattern used to mark and cut identical shapes repeatedly
    • A type of computer program used for drawing detailed three-D shapes on screen
    • A finished product sold in shops in matching sets for households to buy

  16. Why might a designer use a net when making a box?

    • A net is a chart listing the costs of each material
    • A net is a fabric used to cover finished products
    • A net is a mesh used to catch small parts during making
    • A net is a flat pattern that folds into a 3-D box

  17. A card net of a cube has six squares, each 5 cm wide. What is the area of one square?

    • 25 cm squared
    • 5 cm squared
    • 10 cm squared
    • 30 cm squared

  18. What is a disadvantage of modelling with card instead of the final material?

    • Card models can never be made to any scale at all for the design drawing
    • Card cannot be cut, scored or folded in any way at all by a pupil in class
    • Card is always much more expensive than the final material for any product
    • Card may behave differently under load, so it can mislead strength tests

  19. Why do designers label their models?

    • To show the names of all the people who visited the workshop that day
    • To raise the price of the model in a sale to the public and the press
    • To hide the parts that the designer dislikes most in the final model display
    • To record key measurements and decisions for later reference

  20. A model shows a fold line on a net. What does this tell the maker?

    • Where the product should be stored in a warehouse before shipping it out
    • Where to print the product's brand name on the outside of the box
    • Where the material should be folded to make the shape
    • Where to glue the product to a display stand in the classroom display
