Section B

 

DESIGN AND DRAWING

A bookcase is to be designed to the following specifications:

height             -           350 mm;
width               -           360 mm;
depth              -           210 mm.

The bookcase is made from 20 mm solid wood.

  It has one shelf and one panel glazed door.

(1)         Make two Preliminary freehand pictorial sketches each for a different design of the bookcase.

(2)        Select one of the sketches in questions 1 and indicate the selected sketch with a tick (√).  To a scale of 1:2, draw in the First Angle Orthographic projection the following:

(A)front elevation;

(B)plan with top removed.

Observation

 

Candidates were expected to do the following:

  • make two different preliminary freehand sketches of a bookcase
  • select one with a tick
  • draw the front elevation
  • draw the plan with to removed
  • draw to specification
  • dimension properly
  • name the views.

Most of the candidates performed poorly in this section.  They seem not to understand the concepts of:

  • bookcase
  • glazed door
  • panel door
  • shelf.

 

The concepts were missing in their sketches and some used straight edge instead of sketching with freehand.

The solution is stated below:
I           Preliminary Freehand Pictorial Sketches

-           draw for resemblance;                                                
-           draw completely;                                                       
-           draw to proportion      ;                                              
-           draw overall dimension properly;                                          
-           draw good line quality.                                                          

II         (A)       Front Elevation (FE)

  • indicate the sketch selected                                    
  • draw carcase members (2 stile, top, bottom ,shelf in hidden detail)
  • draw door members (2 stile and 2 rails)                                 
  • draw door details (one glazed panel, 2 hinges, lock, handle) 
  • Indicate the  joints (at least 2)                                   
  • draw to scale                                                                          
  • dimension properly                            
  • show line quality                                                                    
  • name the view                                             

(A)       Plan With Top Removed

  • position the  first angle in the appropriate plane        
  • project from front elevation  
  • show carcase members (2  sides and back cover) 
  • draw door members (rails and stile)   
  • draw door details (top rail, hinges, handle)  
  • show shelf                                          
  • indicate joints ( at least 2)      
  • draw to scale                                      
  • dimension properly                
  • show line quality                                                                    
  • name the view
