Introduction to Engineering Drawing

ENGINEERING DRAWINGS AND ENGINEERING DATA

             While most engineers enjoy the process of getting to the first working model, few employers view that as sufficient. Instead, engineer's efforts are useful only when the design has been captured in engineering drawings and supporting engineering data because:

Engineering drawings describe how to consistently reproduce the design. Consistent reproduction is essential, since it forms the basis for product improvements and production efficiency.

Engineering data proves that the product conforms to the original design goals. Proof of conformance is important to both internal stakeholders (marketing, accounting, production) and external groups (distributors, customers, service providers, regulatory agencies).

Define engineering drawing. Why drawing is called universal language of engineers?

          A drawing drawn by an engineer having engineering knowledge for the drawing purposes is an engineering drawing. It is meant for communicating his ideas, thoughts and designs to others. Engineering drawing is a starting point of all engineering branches such as Mechanical, Production, Civil, Electrical, Electronics, Computer science, Chemical etc. It is spoken, read, and written in its own way. Engineering drawing has its own grammar in the theory of projections, its idioms in conventional practices, its punctuations in the types of lines, its abbreviations, symbols and its descriptions in the constructions.
