Topic 3.2: Graphical modelling

Question 1

Graphical modelling

Answer 1

A visualization of an idea, often created on paper or through software in 2 or 3 dimensions

Question 2

2D physical modelling

Answer 2

an extension of sketching that provides designers with some solutions to their thinking

Question 3

2D virtual modelling

Answer 3

mostly diagrammatic, conveying or representing what happens in reality

Question 4

3D physical modelling

Answer 4

tactile, hands on representation of an object. Includes: scale models, clay models, concept models and prototypes

Question 5

3D virtual modelling

Answer 5

the use of a wide range of CAD tools that assist engineers, architects and product designers in developing a realistic 3D render visualization of their ideas

Question 6

One point perspective

Answer 6

lines converge towards a single vanishing point directly ahead, all other lines are either vertical or horizontal

Question 7

2 point perspective

Answer 7

drawings that have lines that converge towards 2 vanishing points that sit on a horizon line

Question 8

3 point perspective

Answer 8

adds a 3rd point which relates an extra element of reality to the communicative impact of a product

Question 9

orthographic drawing/projection

Answer 9

includes front, side, top and isometric views
used to communicate dimension, form, shape
can be used for manufacturing

Question 10

Isometric drawing

Answer 10

shows the shape and form of an object, no vanishing points, drawn on 30/60/90 degree grids

Question 11

concept sketching vs formal drawing

Answer 11

concept sketching: spontaneous representations of ideas on paper without use of technical aids

formal drawing: techniques used in the development phase of a design process

Question 12

Assembly drawing & part drawing

Answer 12

assembly: shows how parts of a product fit together

part: provides the information to assembly a product in a similar way to an assembly drawing, with the additional benefit of having a list of parts or bill of materials
