A picture is worth a thousand words.
This holds true for all engineers.Technical drawing allows efficient communication among engineers. Engineering drawing is all about applying mathematical and scientific knowledge to designing. To be successful as an engineer, a person must be able to accurately communicate one’s design intentions to clients, manufacturers, and end users through the use of drawings, specifications, and instructions.
Engineering drawings must be clear and accurate. When engineers fail to accurately communicate their designs, expensive materials can be cut in wrong sizes, joints can be completed improperly and may require expensive changes to be adapted back to the original intent. This can lead to improper structures and failed machinery, resulting in loss of property, loss of money, or even serious accidents. So how does an engineer excel at drawing? By getting the basics right.
Engineers must go to great lengths to create and test every part of a design before completing a final prototype or a full-size model. Engineers are able to identify where designs might fail and decide how to make them better by building up models at a small scale with those designs and then conducting tests on them. Through the cycle of designing, building models, testing, and re-designing, engineers are able to produce final prototypes, drawings, and instructions which are accurate as per the requirements.
Hence, good engineers are required to spend a lot of time creating drawings with detailed dimensions and material specifications that communicate their design intent accurately to others.
Courses in engineering drawing focus specifically on renderings for engineering projects. Students study the proper use of dimensions, shapes, and angles, as well as different part views and object scaling. Dimensioning and tolerancing practices also figure prominently into the typical curriculum, with a focus on proper interpretation and accurate reflection of dimensions in the drawing.
Engineering students should know drawing components including common abbreviations and symbols in order to:
- Design parts of machinery
- Make changes to existing mechanical drawings
- Sketch new designs
- Engineering Drawings Foundation
- Engineering Drawings for Castings
- Engineering Drawings for Machining
- Engineering Drawing for Spur & Helical Gears
