Engineering involves applying scientific and mathematical principles to design and implement inventions and systems to meet objectives, while drafting involves preparing technical drawings and plans used in manufacturing and construction. Both fields have a long history dating back to ancient civilizations. Engineers use modeling, testing and problem solving methods to develop innovative solutions, while drafters focus on creating detailed technical drawings and plans to communicate engineering designs. There are many specialized fields within both engineering and drafting.
Engineering v drafting
- 1. ENGINEERING VS. DRAFTING Similarities and Differences
- 2. Engineering Engineering is the science, discipline, art and profession of acquiring and applying technical, scientific and mathematical knowledge to design and implement materials, structures, machines, devices, systems, and processes that safely realize a desired objective or inventions. Offshore wind turbines require technical input from engineers of different fields
- 3. Drafting Drafters prepare technical drawings and plans, which are used to build everything from manufactured products such as toys, toasters, industrial machinery, and spacecraft to structures such as houses, office buildings, and oil and gas pipelines.
- 4. History of Engineering The concept of engineering has existed since ancient times as humans devised fundamental inventions such as the pulley, lever, and wheel. Each of these inventions is consistent with the modern definition of engineering, exploiting basic mechanical principles to develop useful tools and objects
- 5. History of Engineering The Pharos of Alexandria, the pyramids in Egypt, the Hanging Gardens of Babylon, the Acropolis and the Parthenon in Greece, the Roman aqueducts, Via Appia and the Colosseum, Teotihuacán and the cities and pyramids of the Mayan, Inca and Aztec Empires, the Great Wall of China, the Buddhist Stupa and Yoda Cannel in Sri Lanka, among many others, stand as a testament to the ingenuity and skill of the ancient civil and military engineers. The lighthouse was completed in the 3rd century B.C
- 6. History of Drafting Drawing to communicate technical ideas may predate the written language. The oldest drawing instruments known, a drawing board in scripted with a temple plan, date from the 3rd millennium BC from the city of Lagash in Babylon. The ancient Greeks influenced drawing through their work in geometry, and tools such as the compass and triangles used in engineering were then developed.
- 7. History of Drafting Over the next million years this process changed little except by the method used to draw, paint, and preserve the illustrations. The greatest changes are noted during the Egyptian and Chinese Empires and the development of rice paper and the methods of presenting ideas. This was the beginning of drafting as we know it today and other than the tools used to make drawings more accurate and legible very little changed until the creation of the modern electronic devises that we have used over the last 75 years. Drafting is the basis of everything that is usable. D.Class
- 8. History of Drafting There are almost one hundred different work disciplines for drafters and designers. These include Aerospace, Highways, Parks and Recreation, Electronic, Nano-Technology, Medical, Furniture, High Voltage Electricity, Automotive and many more. Think about going to the hospital, look around at all the equipment and gadgets, consider having surgery and all the tools that are used, having a knee implant that is specifically designed to fit your bones or even wearing a band-aid, all of these are manufactured by the aid of a drawing. Engineers, Architects, Scientist, Doctors, Physicist, and even Composers used drafting to create the final product. All of the worlds greatest inventions, thoughts and improvements end up as a drawing and the drafter is that invisible person who in reality makes dreams come true.
- 9. Modern Era of Engineering Electrical Engineering can trace its origins in the experiments of Alessandro Volta in the 1800s, the experiments of Michael Faraday, Georg Ohm and others and the invention of the electric motor in 1872. The work of James Maxwell and Heinrich Hertz in the late 19th century gave rise to the field of Electronics. The later inventions of the vacuum tube and the transistor further accelerated the development of Electronics to such an extent that electrical and electronics engineers currently outnumber their colleagues of any other Engineering specialty. The inventions of Thomas Savery and the Scottish engineer James Watt gave rise to modern Mechanical Engineering. The development of specialized machines and their maintenance tools during the industrial revolution led to the rapid growth of Mechanical Engineering both in its birthplace Britain and abroad.
- 10. Engineering and Problem Solving Engineers use their knowledge of science, mathematics, and appropriate experience to find suitable solutions to a problem. Engineering is considered a branch of applied mathematics and science. Creating an appropriate mathematical model of a problem allows them to analyze it (sometimes definitively), and to test potential solutions. Engineers typically attempt to predict how well their designs will perform to their specifications prior to full- scale production. They use, among other things: prototypes, scale models, simulations, destructive tests, nondestructive tests, and stress tests. Testing ensures that products will perform as expected. Link
- 11. Computer Modeling One of the most widely used tools in the profession is computer-aided design (CAD) software which enables engineers to create 3D models, 2D drawings, and schematics of their designs. CAD together with Digital mockup (DMU) and CAE software such as finite element method analysis or analytic element method allows engineers to create models of designs that can be analyzed without having to make expensive and time- consuming physical prototypes.

- 12. Engineering Design An engineering design process is a process used by engineers to help develop products. the engineering design is defined as … the process of devising a system, component or process to meet desired needs. It is a decision- making process (often iterative), in which the basic sciences, mathematics, and engineering sciences are applied to convert resources optimally to meet a stated objective. Among the fundamental elements of the design process are the establishment of objectives and criteria, synthesis, analysis, construction, testing, and evaluation.

- 14. Types of Drafting Drafting work has many specialties: Aeronautical drafters prepare engineering drawings detailing plans and specifications used in the manufacture of aircraft, missiles, and related parts. Architectural drafters draw architectural and structural features of buildings and other structures. These workers may specialize in a type of structure, such as residential or commercial, or in a kind of material used, such as reinforced concrete, masonry, steel, or timber. Civil drafters prepare drawings and topographical and relief maps used in major construction or civil engineering projects, such as highways, bridges, pipelines, flood control projects, and water and sewage systems. Electrical drafters prepare wiring and layout diagrams used by workers who erect, install, and repair electrical equipment and wiring in communication centers, power plants, electrical distribution systems, and buildings. Electronics drafters draw wiring diagrams, circuit board assembly diagrams, schematics, and layout drawings used in the manufacture, installation, and repair of electronic devices and components. Mechanical drafters prepare drawings showing the detail and assembly of a wide variety of machinery and mechanical devices, indicating dimensions, fastening methods, and other requirements. Process piping or pipeline drafters prepare drawings used in the layout, construction, and operation of oil and gas fields, refineries, chemical plants, and process piping systems.
- 15. Education The kind and quality of drafting training programs vary considerably so prospective students should be careful in selecting a program. They should contact prospective employers to ask which schools they prefer and contact schools to ask for information about the kinds of jobs their graduates have, the type and condition of instructional facilities and equipment, and teacher qualifications. Technical institutes offer intensive technical training, but they provide a less general education than do community colleges. Either certificates or diplomas may be awarded. Many technical institutes offer 2-year associate degree programs, which are similar to, or part of, the programs offered by community colleges or State university systems. Their programs vary considerably in length and in the type of courses offered. Some public vocational-technical schools serve local students and emphasize the type of training preferred by local employers. Most require a high school diploma or its equivalent for admission. Other technical institutes are run by private, often for-profit, organizations sometimes called proprietary schools.
- 16. So how are they similar and how are they different? Engineers VS. Drafters You tell me…. By design/drafting are you referring to making mechanical drawings of parts/structures or design/drafting in the artistic sense? In the first case, I would say design/drafting is related to engineering; however, the engineering design process is much more involved. All engineering disciplines will involve some aspects of design. First, there are many kinds of engineering such as electrical engineering, mechanical engineering, civil engineering, and biomedical engineering. For example, electrical engineers may design circuits which may involve drawing of the circuit on a computer. Civil engineers may design buildings. "Design" is a big part, and in order to do it correctly we need to apply the mathematical and scientific concepts that we learn. For example, for a mechanical engineer to design a part or a system, he/she needs to determine the material strength, system safety, etc. Once the design is created, the engineer may send it to a drafter who then creates a mechanical drawing which a machinist can use as a reference when building the part. I would suggest visiting some universities in your area to learn more about engineering.
