graphical modelling

Question 1

Working drawings used in graphical modelling

Answer 1

isometric views, exploded views, perspective drawings (one point), two point drawings, three point drawings and orthographic projections

Question 2

isometric views

Answer 2

• an isometric drawing depicts the proposed solution in 3D showing shape and form
• They are drawn on a 30/90/30 degree axis

Question 3

exploded views

Answer 3

• we do an exploded view to demonstrate how different parts fit together or are assembled
• It is also accompanied by a material list in a design folio

Question 4

Perspective drawing - one point

Answer 4

• horizon and single vanishing point
• Parallel lines alone one of the axis would all converge towards the vanishing point

Question 5

two point drawing

Answer 5

• horizon and two vanishing points
• Parallel lines along two axes would converge towards the vanishing points

Question 6

3 point drawing

Answer 6

• horizon and 3 vanishing points
• Parallel lines along 3 axes would converge towards the vanishing points

Question 7

Orthographic projection

Answer 7

orthographic projection represents a 3D object by 2D drawings in which the object is viewed along parallel lines that are perpendicular to the plane of the drawing

Question 8

A part

Answer 8

contains details about a part of a product not the whole product

Question 9

Sectional view

Answer 9

shows the internal details of the part
