Q

Describe the features of expanded polystyrene

A

Used for block modelling, requires file or rasp, abrasive paper, filler (plaster of Paris) & acrylic paint to make

The advantage of it is that it is great for 3D models, the disadvantage is that it is difficult to achieve a high quality surface finish.

Safety precautions: cut in well ventilated place, wear mask to protect from dust.

It is not biodegradable.

Q

Describe the features of Balsa wood

A

Used for block modelling, requires file or rasp, abrasive paper, acrylic paint to make

Q

Describe the features of plasticine or clay

A

Used for block modelling, requires fingers and wooden shaping tools to make

The advantage of it is that it is very quick to shape in 3D, can be vacuum formed and is easily recycled, the disadvantage is that it is difficult to achieve a good finish

Q

Describe the features of foam board

A

Used for point of sale stands, requires craft knife, safety ruler to make (and laser cutter/die cutter to make complicated shapes)

The advantage of it is that it is rigid, excellent surface to draw on, easy to apply a printed image to, the disadvantage is that it is difficult to hand cut curves without ripping the foam, not recyclable

Safety precautions: take care when cutting

Not biodegradable

Q

what is an isometric

A

A pictorial drawing with horizontal lines which shows objects in 3D. Lines are vertical or at 30 degrees to the horizontal. isometric grids can also be used to construct round objects and more complex shapes

Q

what is a one point perspective

A

a form of 3D drawing created with a single vanishing point

36
Q

What is a two point perspective

A

creates a 3D drawing using 2 vanishing points

37
Q

what is the vanishing point

A

the point where all the lines meet or converge

38
Q

What is the horizon

A

a horizontal line on which the vanishing point sits

39
Q

what is third angle orthographic projection

A

a standard technique for producing detail and working drawings that everyone can understand

40
Q

what are the 3 angles of orthographic projection

A

front view - looking at the front of the product.
Plan view - drawn directly above the front view.
End/side view - drawn by looking at the side or end of a product

41
Q

what does a continuous line mean in British standard conventions

A

Outlines

42
Q

What does a continuous thin line mean in British Standard conventions

A

dimension, projection, hatch line

43
Q

What does short dashes mean in British Standard conventions

A

hidden detail

44
Q

What does long chain mean in British Standard conventions

A

centre lines

45
Q

What does long chain, thick end lines, arrows mean in British Standard conventions

A

section lines

46
Q

What does wavy lines mean in British standard conventions

A

sort break lines

47
Q

what are sectional drawings

A

drawings produced by cutting through an object and the area where the object is cut is shown by hatching

48
Q

what are exploded drawings

A

production of a 3D drawing showing construction methods and components which are drawn separately but in relation to one another and shows how the product should be assembled

49
Q

what is self assembly

A

constructing an item from a kit using instructions supplied

50
Q

what are the benefits of self assembly

A

company can store many more products in a certain space and make more money. Customer pays less for the item because the company pays less for professional assembly and so prices can be lower. 3D drawn instructions are simpler and cheaper to produce than worded ones

Q

how is a surface development is folded into a 3D shape

A

need to be creased, folded and glued

57
Q

what machine is used for irregular shaped surface developments

A

die cutter
