INDUSTRIAL design, NEW product development, TECHNOLOGICAL innovations, COMPUTER-aided design, COMPUTER-aided engineering, INDUSTRIAL research, PROTOTYPES, MANUFACTURING processes, and COMPUTER simulation
The article presents information on the designing of innovative new products. Engineers have adopted productivity tools that promise more predictable outcomes. Computer-aided design, is one of those tools. The evolution of design documentation made advance when engineers defined their designs in the universal graphics language known as orthographic projection drawings. Engineers now create a three-dimensional simulation of the solid design instead of creating two-dimensional representations of views. Working from the design saved days in the project schedule. Engineers do prototyping to test designs.
