1.17 Developing, communicating, recording and justifying design

Which technique is used to make collages?

• Freehand sketching

• Cut and paste techniques

• Digital photography/media

• Orthographic projections

What is used to record each stage of development or videos of testing to demonstrate how a design works?

• Freehand sketching

• Annotations

• Digital photography/media

• Perspective drawing

What type of drawing shows how objects get smaller as they get further away?

• Isometric projection

• Oblique projections

• Perspective drawing

• Orthographic projections

In one-point perspective drawing, where do the objects being drawn converge?

• At a single vanishing point on a horizon line

• At two vanishing points on either side of the horizon line

• At a 30-degree angle

• At a 45-degree angle

Which method shows a 3D object in 2D using front, plan, and side views?

• Isometric projection

• Oblique projections

• Perspective drawing

• Orthographic projections

In third angle orthographic projections, where is the front view drawn?

• Below the plan view

• Above the plan view

• To the right of the plan view

• To the left of the plan view

What does an exploded view in orthographic projections show?

• The front side of the object

• The parts of a product suspended in space and slightly separated by distance

• The objects being drawn converge towards a single vanishing point

• The sides of the object at a 30-degree angle

What does orthographic projection show about the various parts of a product?

• The relationship between all the various parts

• The front side of the object

• The objects being drawn converge towards a single vanishing point

• The sides of the object at a 30-degree angle

What is the purpose of assembly drawings?

• To show a system in terms of its input, processes, and output sub-systems

• To use symbols to show a circuit in terms of its individual components

• To show how all the different parts of a product fit together

• To justify design ideas and decisions

Which of the following is an advantage of computer-aided design (CAD)?

• It presents a top-down overview of the system

• It uses symbols to show circuits

• Accuracy of drawing and modelling is very high

• It shows how all parts of a product fit together
