| 3.5 | Explain how to access the specific computer drawing software to be used, and the use of software manuals and related documents to aid efficient operation of the relevant drawing system |
| 3.6 | Explain how to deal with system problems (such as error messages received, peripherals which do not respond as expected, obvious faults with the equipment or connecting leads) |
| 3.7 | Describe the documentation required for particular applications (such as drawing briefs, specification sheets, request for change orders) |
