1IMPORTANCE OF ENGINEERING GRAPHICS
In Engineering Profession, it is very essential that the
Engineers and Craftsmen are able to communicate their ideas and
facts with each other clearly and without ambiguity. The verbal
communication may be hopelessly inadequate. The written
communication, on the other hand may be very inefficient, lengthy
and boring to create accurate mental and physical impression of an
item in the mind of the reader.
The Engineering Drawing, which is a Graphical
Communication of an accurate and unambiguous description of an
object, has proved to be an efficient communication method. It is a
means of organizing and presenting precise technical directions for
items to be produced for the consumers.
Engineering Drawing can supply all the information needed
with the exactness and details required. It is therefore, one of the
principal functions of drawing to convey ideas from the design
engineer to the fabricator. Hence, the skill to interpret and
construct engineering sketches and drawings is of paramount
importance.
The engineer may convey his ideas by one or more of the
three basic types of projections namely; Orthographic Projection,
Oblique Projection or Perspective Projection, depending upon the
purpose of the drawing and the person to whom he wishes to
convey his ideas. Certain professional areas have different
nomenclature such as Machine Drawing, Architectural Drawing,
and Structural Drawing.
