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.
