Term
Annotated Sketches
Definition
Sketches that include notes or labels, dimensions and/or symbols.
Term
Technical Drawing
Definition

A visual communication language which is used to communicate how something works or is constructed, includes standard symbols and units of measurement.

 

Term
CAD
Definition
computer-aided design.
Term
Orthrographic Projection
Definition
A way to represent a three-dimensional object in two dimensions. Typically, two or more elevations or pictures are produced to represent the entire object—known as multiview projection.
Term
Isometric Projection
Definition
A simple way to show a three dimensional object;three sides of a object are shown proportionally. All vertical lines are drawn vertically, and all horizontal lines are drawn at an angle of 30° degrees.
Term
Model
Definition
Used throughout the Engineering Design Process to make observations and develop predictions, can be conceptual (are abstract models that use language and graphic-based representations to convey meaning), mathematical (are abstract models that use the language of mathematics to describe the behavior of the solution) or physical (are three-dimensional models, which represent the solution).
Term
Technical Writing
Definition
A very precise style of writing. Good technical writers practice clarity, brevity, simplicity and active voice.
Term
Graphs and Charts
Definition
A conceptual model commonly used to show a relationship between two or more variables and to highlight a trend(s) for the audience.
Term
Line Graph
Definition
Used to show the relationship between two or more objects and/or a trend.
Term
Bar Graph
Definition
Used to show the relationship between objects by measuring frequency.
Term
Pie Chart
Definition
Used to compare parts/percentages within one set of data.
Term
Venn Diagram
Definition
Used to show overlap between two or more sets of data
Term
Mock-Up
Definition
A model that represents of the final solution that does not function.
Term
Prototype
Definition
A model that performs the final solution and can be used for testing/evaluation.
Term
Area
Definition
The amount of space inside a two-dimensional shape.
Term
