In Form One, 1968, we were introduced to Technical Drawing, whereby we learned concepts such as 2D projections of 3D objects, cross-sections, dimensioning protocols, line types, etc.
Looking back, it seemed that I took to Technical Drawing like a duck to water. Everything was like second nature to me, as I drew lines and curves with pencils of various hardness grades.
One basic tool used in drawing practice was the indispensable T-Square, which served as the movable horizontal datum, upon which set-squares were placed, to produce lines which were to be at 90/30/60/45-degree angles to it. And of course, that wooden “drawing table” which supported the drawing paper.
Later on, in the Technical Institute, Penang and even in the University of Malaya, many hours would be spent hunching over the Drafting Table, with T-Square sliding up and down.
