Question 1

 

Design an open wall cabinet to be used in a school’s sports office.  The cabinet has two partitions and two shelves.  It is made with 18 mm plywood.  The overall dimensions of the units are:

            width   -           450;
depth   -           200;
height  -           300.
(All dimensions are in millimeters)

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

(2)        Select one of the sketches in question 1 and indicate the selected sketch with a
tick (√); to a scale of 1 : 5:

            (a)        (i)         draw the isometric view;
(ii)        dimension the view indicating the sizes of the members and
compartments.

  1. Name two joints to be used in constructing the cabinet.

 

 

Observation

Candidates were expected to do the following:

  1. use a pictorial freehand sketch to describe the design of the wall cabinet

described;

  1. sketch to meet the specifications given;
  2. draw in isometric;
  3. dimension appropriately;
  4. name the joints used.

The solution is shown below:

Two preliminary freehand sketches

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

 

                        Isometric  view

-           indicate the sketch selected;
-           use the correct isometric axes;
-           show front details (2 sides, top, bottom
2 partitions, 2 shelves, method of fixing);
-           show side details (including hidden details);
-           show top details (including hidden details);
-           indicate the joints (at least 3);
-           use the appropriate scale;
-           show good line quality;
-           naming the view.

Dimensioning

                        -           show overall dimensions;
-           dimension the members;
-           dimension the compartment.

                        Name of joints

                        -           through dovetail;
-           lap dovetail;
-           secrete dovetail;
-           pinning;
-           rebated butt;
-           nailed butt;
