In computer-aided design (CAD), when a model is created that has no interior material and is just a visual representation of the final product, this is considered as a…

What best describes a physical model that can be used to test ergonomic features but does not function?

What rapid prototyping process uses lasers to solidify layers from a liquid resin?

Figure 3 shows people in a museum. By interacting with the exhibit they are able to understand how the image displayed on the screen feels.

Which technology enables the people to understand what the image feels like through their sense of touch?

Which of the following modelling techniques would most likely be used to understand how well a new concept functions?

Which of the following would enable a designer to understand the structural forces acting on a bridge support?

Which of the following processes, commonly used in video games and animated movies, uses magnetic markers or LEDs to create a digital image of a person?

Which of the following rapid prototyping techniques does not require structural supports during the build?

Graphical models are useful for engineers, manufacturers, designers and clients, and vary depending on the context. Which of the following graphical models is most appropriate in the context of an architectural design to present to a client?

Selective laser sintering can use a range of powdered materials to create products. These materials include…

Which type of analysis would you use to simulate unknown factors, such as stresses within a joint, in products?

Figure 3 shows a photorealistic model of a computer mouse. The model gives no internal data for manufacture using computer-aided manufacturing (CAM). What type of model is shown in Figure 3?

What type of prototype is designed to collect quantitative data to help inform development?

What type of graphical model would likely be part of the instructions for flat pack furniture, usually shown in an exploded form?

Which of the following describes a conceptual model?

I. A model that is used to help us develop and understand ideas

II. A scale or full-size representation of a product used to gain feedback from users

III. Photorealistic computer-aided design (CAD)-based interactive models

Many furniture manufacturers provide graphical models to help customers assemble their products, see Figure 3.

What perspective style is used in the image?

Virtual reality is increasingly being used in design and development to simulate product interaction. Sometimes this is used in relation to tools that allow designers and testers to “feel” the virtual environment.

Which of the following best describes a technology that simulates the sense of touch?

Conceptual models provide a way of communicating, testing and developing early ideas.

Who are the main beneficiaries of a conceptual model?

I. Client

II. Designer

III. End user

Figure 3 shows a car design modelled from clay. Which of the following best describes a model that shows exactly how a product could look but not function?

Clay models, scale models and prototypes are all examples of which type of modelling?
