Drawings: The Universal Language
Engineers make drawings to understand and communicate ideas
Drawings are used throughout the entire engineering design process. Freehand sketching is used for generating ideas and for communicating themComputer-aided design (CAD) is used to for both design documentation and to evaluate design alternatives.
Engineering design still retains its artistic roots
Design requires both analysis and
synthesisSlide5
