This unit of competency has been developed for engineering tradesperson - mechanical apprenticeship training and the recognition of trade-level skills in marking off/out in general engineering.

Marking off/out is undertaken using appropriate tools and equipment and templates are produced as required. Marking off/out techniques may apply to a range of materials and shapes.

Skills covered by this unit are generally applied in occupational and work situations associated with trade-level fitting, machining and toolmaking work.

Where the task involves a simple transfer of a dimension or marking a location point associated with general engineering and maintenance functions, select one or more of the following units as appropriate:
MEM07005 Perform general machining
MEM18006 Perform precision fitting of engineering components
MEM18014 Manufacture press tools and gauges.

Where the manufacture of marked out components is required, appropriate units should also be selected.

Where a higher level of calculation is required unit MEM12026 Perform advanced trade calculations in a manufacturing, engineering or related environment should also be selected.

Where a higher level of measurement is required unit MEM12003 Perform precision mechanical measurement should also be selected.

Where a higher level of precision work is required unit MEM18003 Use tools for precision work should also be selected.

Where marking out structural fabrications and shapes is required unit MEM12007 Mark off/out structural fabrications and shapes should also be selected.

Where the selection and use of tools is required unit MEM18001 Use hand tools and unit MEM18002 Use power tools/hand held operations, should also be selected as appropriate.

No licensing, legislative or certification requirements apply to this unit at the time of publication.


For Melbourne campuses

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit’s learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.

Students will be expected to demonstrate the following required skills:

  • following work instructions, standard operating procedures (SOPs) and safe work practices;
  • identifying and interpreting specifications and drawings for marking out requirements, including measurements and tolerances;
  • carrying out all marking off/out using tools and equipment to specifications;
  • calculating measurements not shown on drawings, as required;
  • establishing and marking datum points, and;
  • transferring measurements, as required.

Required reading

The qualified trainer and assessor will provide teaching and learning materials as required in the form of workbooks produced by the Polytechnic and/or via the Polytechnic e-learning system.
