Communication Of Design (sketches)

Question 1

What are freehand sketches?

Answer 1

They are normalled used for initial ideas and to develop concepts.
Its drawing without measuring instruments or drawing aids and can be quick to get initial ideas down.

Question 2

What is isometric projection?

Answer 2

All lines are drawn at a 30° angle away from the nearest corner of the object.
It enables designers to draw an object in 3 dimensions which aids visualisation

Question 3

One point perspective

Answer 3

• You can’t see the sides

- Items seem to get smaller and converage towards a single vanishing point.

Question 4

Two point perspective

Answer 4

• Two point uses two vanishing points, so shapes that project towards them appear smaller.

Question 5

What are 2d drawings good for?

Answer 5

They are good for expressing ideas, dimensions, mechanical and electrical concepts

Question 6

Wht are 3d drawings used

Answer 6

They are food at representing the look and feel of an object.

Question 7

What are system diagrams?

And whatndo they contain?

Answer 7

This is a graphical representation of a process.

Different elements such as input, output, devisions and processes can be modelled to create a logical system.

Question 8

What are schematic diagrams?

Answer 8

These are representations of a system.

In electronics, symbols are simplified to represent the components such as a resistor or switch.

Question 9

What do exploded diagrams show?

Answer 9

An exploded drawing shows how component parts of a product fit together/are assembled.

These are usually in flat-pack furniture

Question 10

What are annotations?

Answer 10

Annotations are notes and labels which provide information about the design or process

Question 11

What are Mathematical drawings/modelling

And uses

Answer 11

This is used as a part of the iterative design process.

Uses:

• Simulations and predictions can be calculated and displayed
• Performance can be evaluated and compared.

Question 12

Audio and visual recording uses

Answer 12

• Interviews with user group
• Feedback on the design
• Recordings of focus groups
• Explain ideas verbally
• Video testings
• Analyse and disassemble a product

Question 13

What are Working drawings?

Answer 13

Working drawings give technical details to enable a product to be manufactured.

For further accuracy the drawings should be presented in orthographic projection

Question 14

What are 3rd angle orthographic drawings?

Answer 14

Orthographic drawings typically include the plan view, woth front and side elevations

Question 15

What is good about CAD?

Answer 15

A product can be shown from all angles on screen, and colour, materials and components can be quickly changed.
