What is technical drawing?
Technical drawing is the discipline of creating drawings that visually communicate how some object functions, or how it is constructed.
Technical drawings are essential for clearly communicating ideas in industry, engineering, and manufacturing. To make the drawings easier to understand, people use a common set of symbols, perspectives, units of measurement, notation systems, styles, and layouts. Together, these conventions create a visual language, and helps ensure that the drawings are unambiguous and easy to understand.
The underlying principles of technical drawing (engineering drawing or drafting, depending on where it will be used) has changed little in the last 100 years. The technology used to display and draw the objects certainly has changed, but the underlying principles and strict standards have not.
After practicing these traditional aspects, we switch gears, and use the same tools to design an electronics enclosure, and 3D-printing to realize this enclosure in plastic!
This course helps students to improve their drawing ability and ability to communicate design for manufacturing, and to understand how these design can be manufactured.
