product’s design process.

Engineering drawing entails the use of graphical

symbols such as points, lines, curves, planes and
shapes. Essentially, it gives detailed description
about any component in a graphical form.

4.1.1 Background

Engineering drawings have been in use for more than

2000 years. However, the use of orthographic
projections was formally introduced by the French I-SECTION TYPE POLE
mathematician Gaspard Monge in the eighteenth
century.

Since visual objects transcend languages, engineering

drawings have evolved and become popular over the
years. While earlier engineering drawings were
handmade, studies have shown that engineering
designs are quite complicated. A solution to many
engineering problems requires a combination of C-SECTION TYPE POLE
organization, analysis, problem solving principles
and a graphical representation of the problem.
Objects in engineering are represented by a technical
drawing (also called as drafting) that represents
designs and specifications of the physical object and
data relationships. Since a technical drawing is
precise and communicates all information of the
object clearly, it has to be precise. This is where
CAD comes to the fore.
