| refers to a process that uses a computer and drawing software to assist the drafter in preparing mechanical or archetectural drawings. | | |
| In addition to being quicker, CAD systems increase what? | | |
| This is the heart of the CAD system | | |
| Produces full-size, 3D plastic models directly from CAD drawings | | |
| Short words which, when entered, causes the computer to perform some function. | | |
| An object or text item created using CAD software. | | |
| is used to lock the drawing cursor to grid points as it is moved across the screen. When this is turned on, the cursor jumps from grid point to grid point as it moves across the screen. | | |
| Help the drafter easily locate position on the drawing. These patterns are normally dots on the screen. | | |
| Used to rotate an entity around a base point. | | |
| Allows the drafter to move in on a particular part of a drawing. By moving in on the drawing the drafting can view more details. | | |
| Most Cad programs allow the screen to be split into spearate these? | | |
| A method of graphical point location. All CAD systems use this system as a standard. | | |
| Represents the position of a point. The first number represents the X coordinate while the second is the Y coordinate. | | |
| Give the position measured from the origin of the drawing. These coordinates refer to precise locations on the Cartesian coordinate grid. | | |
| Refer to a point or location measured from a previous point. For example, coordinates could be specified for a second point that is 8,4 from the original point 4,2. | | |
