engineers: people who use technical means to solve problems. they design products, systems, devices, and structures to improve living conditions

technical drawings: a clear precise language used in the design process for communicating, solving problems, quickly and accurately visualizing objects, and conducting analysis. it is a graphical representation of objects and structures is done using freehand, mechanical, or computer methods.

breakdown of engineers time: 92% of the process is graphical and the remaining 8% is math and communication

design process:

1. problem identification
2. preliminary ideas
3. design refinement
4. analysis
5. optimization
6. documentation
7. implementation: services, financing, marketing, producing, planning, documenting
