| Question | Answer |
| Continuous thick Used for visible outlines and edges. | |
| Continuous thin: Used for projection, dimensioning, leader lines, hatching and short centre lines. | |
| Continuous thin straight with zigzags: Used for limits of partial or interrupted views and sections if the limit is not an axis. | |
| Dashed thin line: Used for hidden outlines. | |
| Chain thin: Used for centre lines. | |
| Chain thin double: Used for ghost outlines. | |
| Continuous thin irregular: Used as the limit to an interrupted view when an axis is not present.l | |
| Chain thin thick at both ends and changes in direction: Used on cutting planes. | |
| Remember the names of these lines! Leader lines are narrow lines which lead from points on a view to the arrowhead dimension lines. A small gap should be left between the view and the leader line. | |
| This is "across corners" dimensioning. | |
| This is "across flats" dimensioning. | |

| Third Angle Projection Symbol (Indicates the method of projection used on orthographic drawings). | |
| Common Tolerance: The common method shows the upper limit of the size placed above the lower limit. | |
| Asymmetrical Tolerance: The asymmetrical method shows the nominal size (size measured) plus the upper and lower limits of the tolerance. | |
| Symmetrical Tolerance: The symmetrical method shows the nominal size and the symmetrical tolerance expressed as a plus and minus. | |
| Functional Tolerance: A dimension that is essential to the function of a component or space. | |
| Non-functional Tolerance: A dimension that is not essential to the function of a component or space. | |
