Design Process
The first step of the engineering design process
Define the Problem
The most common three views in a multiview drawing
Front, Right Side, Top
How close a measurement is to the correct value
Accuracy
The tool that creates a 3D model by giving uniform thickness to a 2D sketch
Extrude
A tool for selecting the best design by scoring them using established criteria
Decision Matrix
The second step of the engineering design process
Generate Concepts
A 3D drawing in which the front, side, and top of an object are all shown at the same angle
Isometric
How close repeated measurements are to each other
Precision
The tool that rounds corners
Fillet
This makes sketches look realistic because each feature is the correct size relative to the others
Proportion
An early working model built for testing
Prototype
Used to indicate an edge that we can't see on a particular view
Hidden Lines
The number of inches in 4 yards
144 inches
The tool that hollows out a 3D object
Shell
This geometric constraint requires two lines to form a right angle
Perpendicular
The goals for the design that we will use to evaluate it
Criteria
A precision measurement tool that measures to within a thousandth of inch by opening a set of "jaws" to match the length of an object
Dial Caliper
In an assembly, this type of mate allows a part to move along only one axis
Slider Mate
This type of fit occurs when a hole is smaller than the part inserted into it
Interference Fit
The term for a process like engineering design that is repeated until you get the desired outcome
Iterative
A view that shows what the inside of an object looks like when part of it is cut away
Section View
The number of centimeters in one kilometer
100,000 centimeters
In an assembly, this type of mate allows a part to revolve around only one axis
Revolute Mate
This type of hole has slanted edges at the top
Countersink Hole
