Introduction

In the technologically advanced world of today, technical drawing with engineering graphics and design employs every important cognitive and manipulative skill in order to aid engineering graphical communication which uses lines, dimensions, scales, symbols and signs to illustrate how products, processes, services and systems look and work.

Technical drawing is applied in many fields, one of which is engineering graphics and design. Many students usually study technical drawing before gaining admission to read engineering and study engineering graphics which is just one out of many engineering subjects. The transition from technical drawing to engineering graphics and further study is usually much easier for students who have had past experience in technical drawing.

Although many people assume that technical drawing is the same as engineering graphics, there is actually a difference between the two: technical drawing is generally employed in producing diagrams and representations of object and shapes on paper, while engineering graphics is a technique used by engineers to produce engineering design drawings, including pictorial representations of data in computer-aided design (CAD) and manufacture with the use of softwares.

Engineering graphics is somewhat an advanced type of technical drawing that clearly expresses the practical requirements for engineering forms or structures. Technical drawing goes hand in hand with engineering drafting graphics and design. Generally, whenever pencil and paper, or computer is used for drafting, it must be ensured that drafts are clear and visible enough to demonstrate how things work/would work.

The procedure, skill or actions often used to produce engineering graphics can be regarded as technical drawing or drafting. Note that technical drawing is also be applied in disciplines that are not usually regarded as fields of engineering; examples include landscaping, architecture, environmental health science, cabinet making, garment-making, etc.

Engineering graphics often combines many colors, various texts, and illustrations in order to communicate clearly and effectively using drawings, especially with people who understand the language of technical, or engineering drawing.

Importance, and Uses/Applications of Engineering Graphics and Design

Importance of Engineering Graphics and Design

Just to mention a few, the importance of engineering graphics and design include (but are not limited to) the following:

  • Engineering graphics and design is important because it provides engineering and technology students with knowledge of techniques and standard practices generally employed worldwide in engineering graphics and design. This makes it easier or possible for design ideas to be adequately communicated, produced and used in many countries.
  • Engineering graphics and design is important because it sharpens the imagination, and helps engineering professionals solve more advanced technological problems related to engineering graphics and design.

Uses/Applications of Engineering Graphics and Design

Although engineering graphics and design has many uses or applications, discussions will be limited to the following:

  • Engineering graphics and design can be used to produce “layout drawings” of completely designed end products; it can also be used in geometric studies to develop the movement of mechanical linkages, clearances, or arrangements.
  • Engineering graphics and design can be used to produce “mono-detail drawing” which is very important because it gives details and maximum clarity about any part of an engineering structure without having to view a whole structure.
  • Engineering graphics and design can be used to produce “assembly drawings” for 2-D projections that have to be joined together in order to form an “assembly” which gives clear and precise overview of structures.
  • Engineering graphics and design can be used to produce “installation drawings” in order to provide technical information on how to properly position and install items. Installation drawings could include dimensional data, hardware descriptions, and information regarding general configuration on installation sites where control systems, electrical systems, hydraulic systems, and other types of systems exist.
  • Engineering graphics and design can be used to produce “modification drawings” in order to alter characteristics of items that have been purchased in bulk; examples include hinges, extrusions, channel nuts, semi-processed items as electronic equipment drawers, castings, blank panels, castings, etc. Drafts for altered items are usually prepared whenever it becomes necessary to alter existing items.
  • Engineering graphics and design can be used to produce “procurement control drawings” which provide criteria on performance, and identification of supplier items that list the engineering design characteristics required to ensure control of interfaces, and repeatability of performance according to design. In the commercial realm of engineering practice, procurement control drawings can be prepared for item identification, purchased items, alteration to purchased items, selection from purchased items, and development/qualification of new items.
  • Engineering graphics and design can be used to produce “mechanical systematic diagrams” whenever general operating principles cannot be promptly determined after studying assembly drawings. Generally, mechanical schematic diagrams clearly illustrate design information for hydraulic or pneumatic systems, and complex mechanical systems such as the complex arrangement of gears, cams, linkages, clutches, linkages, etc.
  • Engineering graphics and design can be used to produce “electrical & electronic diagrams” (in accordance with ANSI Y14.15 or ANSI/IEEE STD 991) in order to clearly describe the elements and functions of electrical or electronic tools/equipment in accordance with ANSI/IEEE STD 91 and 315.

Engineering graphics and design can be used produce “functional block diagrams” in order to clearly illustrate the relationship between the functions of major elements in a system, or an assembly of various systems.
