| 2.2 | Produce two of the following: • detail drawings • general arrangement drawings • sub-assembly drawings • installation/commissioning drawings |
| 2.3 | Use codes and other references that follow the required conventions |
| 2.4 | Produce drawings which comply with one or more of the following: • organisational guidelines • statutory regulations and codes of practice • CAD software standards • BS and ISO standards • other international standard |
| 2.5 | Make sure that drawings are checked and approved within agreed timescales by authorised people |
| 2.6 | Ensure that drawings are properly registered and stored securely |
| 2.7 | Save and store drawings in appropriate locations, to include carrying out all of the following: • ensure that their drawing has been checked and approved by the appropriate person/s • check that the drawing is correctly titled and referenced • save the drawing to an appropriate storage medium • 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 appropriate company information system |
| 2.8 | Ensure that changes are completed as required by organisational procedures |
| 3 | 2a. Know how to produce fabrication/structural engineering drawings using computer aided techniques | 3.1 | Describe the specific safety precautions to be taken when working with computer systems (to include such things as 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 the 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 basic set-up and operation of the computer system, and the peripheral devices that are used (such as mouse, light pen, digitiser and tablet, printer or plotter, and scanner) |
| 3.4 | Describe the correct start-up and shutdown procedures to be used for the computer system |
| 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) |
| 3.8 | Describe the types of drawings that may be produced by the software (such as first and third angle drawings, sectional elevations, isometric or oblique drawings) |
| 3.9 | Explain how to set up the viewing screen to show multiple views of the pattern to help with drawing creation (to include isometric front and side elevations) |
| 3.10 | Describe the national, international and organisational standards and conventions that are used for the drawings |
| 4 | 2b. Know how to produce fabrication/structural engineering drawings using computer aided techniques (continued) | 4.1 | Explain how to set up the drawing template parameters (such as layers of drawings, scale, paper size, colour set-up, line types, dimensioning system and text styles) |
| 4.2 | Describe the application and use of drawing tools (such as for straight lines, curves and circles; how to create hatching and shading on drawings; how to add dimensions and text to drawings, producing layers of drawings) |
| 4.3 | Explain how to access, recognise and use a wide range of standard components and symbol libraries from the CAD equipment |
| 4.4 | Describe the need for document control (such as ensuring that completed drawings are approved, labelled and stored on a suitable storage medium, the need to create backup copies and to file them in a separate and safe location away from electromagnetic sources, filing and storing hard copies for use in production) |
| 4.5 | Describe the procedures for drawing change notes, trial changes, up-issuing of drawings, modifications, and miscellaneous amendments to drawings |
| 4.6 | Describe the relevant sources and methods for obtaining any required technical information relevant to the drawing being produced (such as bend allowances, weld details, locking and securing devices) |
| 4.7 | Describe the basic principles of fabrication engineering manufacturing operations, assembly and installation methods relevant to the drawn item (such as bending and forming methods, joining processes, welding procedures), and how these can influence the way they prepare the drawing |
| 4.8 | Describe the functionality of the component, and its interrelationship with other components and assemblies |
| 4.9 | Describe the extent of their own responsibility and to whom they should report if they have any problems that they cannot resolve when producing the drawings |
