| 2.5 | Make sure that drawings are checked and approved by the appropriate person |
| 2.6 | Save the drawings in the appropriate medium and location to include all of the following: • ensure that their drawing has been checked and approved by their supervisor • check that the drawing is correctly titled and referenced • save the drawing to an appropriate storage medium (such as hard drive, disc, CD, external storage device) • create a separate backup copy and place it in safe storage • produce a hard copy printout of the drawing for file purposes • register and store the drawings in the appropriate company information system (where appropriate) • record and store any changes to the drawings in the company information system (where appropriate) |
| 2.7 | Produce hard copies of the finished drawings |
| 2.8 | Deal promptly and effectively with problems within their control and seek help and guidance from the relevant people if they have problems that they cannot resolve |
| 2.9 | Shut down the CAD system to a safe condition on completion of the drawing activities |
| 3 | 2a. Know how to produce mechanical engineering drawings using a CAD system | 3.1 | Describe the specific safety precautions to be taken when working with computer systems (to include safety guidance relating to the use of visual display unit (VDU) equipment and work station environment (such as lighting, seating, positioning of equipment), repetitive strain injury (RSI); the dangers of trailing leads and cables; how to spot faulty or dangerous electrical leads, plugs and connections) |
| 3.2 | Describe good housekeeping arrangements (such as cleaning down work surfaces; putting disks, manuals and unwanted items of equipment into safe storage; leaving the work area in a safe and tidy condition) |
| 3.3 | Describe the relevant sources and methods for obtaining any required technical information relevant to the drawing being produced (such as drawing briefs, specification sheets, request for changes or modifications to drawings; technical information such as limits and fits, contraction allowances, bearing selection, surface finish) |
| 3.4 | Describe the basic principles of engineering manufacturing operations, assembly and installation methods, and limitations of the equipment/processes that are used to produce the drawn item (such as machining methods, joining processes, fabrication, casting and forging), and how these can influence the way they present the drawing |
| 3.5 | Describe the functionality of the component being drawn, and its interrelationship with other components and assemblies |
| 3.6 | Describe the correct start-up and shutdown procedures to be used for the computer systems |
| 3.7 | Describe the identification of the correct drawing software package from the menu or operating environment; the various techniques that are available to access and use the CAD software (such as mouse, menu or tool bar, light pens, digitisers and tablets, printers or plotters, and scanners) |
| 3.8 | Describe the use of software manuals and related documents to aid efficient operation of the relevant drawing system |
| 3.9 | 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) |
