| Annotated Sketches | are sketches that include notes or labels, dimensions and/or symbols |
| Technical Drawing | is a visual communication language which is used to communicate how something works or is constructed, includes standard symbols and units of measurement |
| CAD | computer-aided design |
| Orthographic Projection | is 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 multi-view projection |
| Isometric Projection | is a simple way to show a three dimensional object. By using isometric projection, 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 |
| Models | re 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) |
| Technical Writing | is a very precise style of writing. Good technical writers practice clarity, brevity, simplicity and active voice |
| Graphs and Charts | a conceptual model commonly used to show a relationship between two or more variables and to highlight a trend(s) for the audience |
| Line Graph | used to show the relationship between two or more objects and/or a trend |
| Bar Graph | used to show the relationship between objects by measuring frequency |
| Pie Chart | sed to compare parts/percentages within one set of data |
| Venn Diagram | used to show overlap between two or more sets of data |
| Mock-Up | is a model that represents of the final solution that does not function |
| Prototype | is a model that performs the final solution and can be used for testing/evaluation |
| Area | the amount of space inside a two-dimensional shape |
| Surface Area | the total area of all surfaces on a three-dimensional object |
| Volume | the amount of space a three-dimensional object occupies |
