Before we find out more about engineering
drawings , would be helpful to know in advance what it was engineering
drawings. The engineering drawings is a fusion between art image and image science that can be used to solve
some of the problems of engineering. If we trace the history of engineering
drawings then we will know that before the engineering drawings, human
civilization has been aware of the art image in advance . That is evidenced by
the discovery of expert evidence of archaeological objects in the form of art
image that is on the rocks and ancient walls . Pictures of art found it shows
that the image of art is a tool used to express thoughts , wishes , feelings
and events that occurred during the period.
initially the engineering drawings
practiced by Leonardo Da Vinci in
the 15th century until the 16th century, so he called the father of the
Engineering drawings. And in the last 16th century, Gaspard Monge is a mathematician from France found a drawing system
using two projection plane perpendicular to each other. Or the system can be
called with a projected bracket or orthogonal projection. In that year the
projection is so well known and often used to draw the design of building ships
and armaments.
Later in the 18th century many
techniques that prioritize the establishment of school subjects in the
curriculum of engineering drawings. It happened because at that time a
scientist James Watt from english
invented the steam engine, which resulted in a massive turnover in the
production process at the factory. Which was originally in the production
process using human and animal power, now replaced using a steam engine. Because
the massive turnover that happened, it requires a language of communication
between planners with implementing whose languages it should be brief and
clear. Then start using working drawings that can be understood by both
parties. From there began the establishment of technical schools that give
priority subjects engineering drawings.
There are so many people who give a
sense of the engineering drawings, following some understanding of engineering
drawings according to some figures:
- FH.
Homan and Ir.
Sutomo Wongsotjitro, technical drawing is the language used between the
designers and implementers.
- James S.Rising
dan Maurice W.Almfedt, engineering
graphic is the combination of these arts and science of drawing applicable of
the solution of engineering problems.
- Thomas E.French
dan Charles I.Fierck, engineering
drawing is the graphic language used into the industrial world by engineers and
designers to express and record the ideas and information necessary for the
building of machines and structures.
- Warren I. Luzadder, technical drawing is a graphic language that is used universally by
engineers to describe the shape and size of structures and mechanism.
So we can conclude that the
engineering drawings should be understood between the designer image by
executing an image in the form of short, clear, and leaves no aspect of the art
of the picture (the beauty of the picture).
