Question 3

 

The figure below shows a machine component.  Draw full size, the isometric view of the component with point P as the lowest.

 

 

Observation

The question involves interpreting a drawing in orthographic drawing to isomeric drawing.  Maintaining a particular low point.

Most of the candidates who attempted this question performed well.

            Candidates were expected to:

DRAW THE ISOMETRIC BLOCK

(i)         use the isometric axes;
(ii)        use the isometric box (100 x 100 x 105);
(iii)       use P as the lowest point;
(iv)       draw face A;
(v)        draw face B;
(vi)       draw face C;
(vii)      draw face D;
(viii)     draw face E;
(ix)       draw face F;
(x)        draw face G;
(xi)       draw face H;
(xii)      draw face J;
(xiii)     draw face K;
(xiv)     draw face L;
(xv)      draw face M with hole;
(xvi)     draw neatly.

The solution is shown below:
