What are the 7 steps of Engineering Design Process ?

• Define the problem

• Research the problem

• Develop possible solutions

• Choose the best solution

• Create a prototype

• Test and evaluate

• Communicate

• Redesign

### CHAPTER 4BEYOND WORDS

Computer-Aided Design, computer programs that allow engineers to create precise drawings of their design ideas.

Software program that allow engineers to construct a model in three-dimensional.

Two-dimensional representation of a 3-D object using views of each side of object.

Front side of the object appears flat in the picture plane and the side and top of the object are a 45-degree angle to the horizontal lines of the front side.

The parallel lines appear to converge on an imaginary point on the horizon is call the vanishing point.

The lines of the object that move away from the viewer converge on an imaginary point

All vertical lines are drawn vertically, but all horizontal lines are drawn at 30 degree to the horizontal.

Ratio of the size of an object in a drawing to the size of the object in real life.

System of measurements in which all of the units are based on multiples of ten.
