Design Proccess
The step where you create a Design Brief and identify constraints.
Define the Problem
A sketch where all three dimensions are visible and the object is tilted at 30 degrees.
Isometric
The average of a data set.
Mean
The tool used to measure high-precision outside diameters and depths.
Dial Caliper
The amount of 3D space an object occupies.
Volume
A technique used to generate many ideas without criticism.
Brainstorming
The most common view used in a multiview drawing to show the most detail.
Front View
The value that occurs most frequently in a set.
Mode
The total amount a specific dimension is allowed to vary.
Tolerance
The mass of an object per unit volume.
Density
A working model used to test a design concept and gather data.
Prototype
These dashed lines show edges that are not visible from a specific view.
Hidden Lines
The physical properties of a 3D model (mass, volume, surface area).
Physical Properties / Mass Properties
A measurement that is "close to the true value."
Accuracy
The process of taking something apart to understand how it works
Daily Double
Reverse Engineering!
This document legally proves the timeline of an invention.
Engineering Notebook
A drawing that shows an object as if it were cut in half to show internal detail
Section View
A line that best represents the trend of data on a scatter plot.
Trend Line / Line of Best Fit
The degree to which repeated measurements show the same result.
Precision
To calculate the volume of a sphere, you use this formula.
V = (4/3)pi r^3
A tool used to compare design ideas based on specific criteria/constraints.
Decision Matrix
Sketching style where parallel lines converge at one or more points on the horizon
Perspective
A statistical measure of how spread out the numbers are in a data set.
Standard Deviation
Convert 5 inches to millimeters
127 mm
Material that is a combination of two or more substances (like carbon fiber).
Composite
