Application
This unit applies to any of the full range of engineering disciplines. All work is carried out under supervision and all specifications, dimensions and tolerances are predetermined. The unit covers application of introductory drafting skills to select and apply drawing protocols.
Manual drafting or computer-aided design (CAD) drawing equipment may be used.
If CAD skills are required, MEM30031A Operate computer-aided design (CAD) system to produce basic drawing elements, should be selected.
Drawings are completed to Australian Standard (AS) 1100.101–1992 Technical drawing – General principles.
Prerequisites
Not applicable.

Required Skills
Required skills |
Required skills include: correctly using and maintaining equipment, including CAD manual drafting, filing and printing reading and interpreting specifications communicating with supervisor to confirm work requirements and outcomes visualising components preparing a drawing in plane orthogonal, isometric projection or equivalent determining drawing protocols required to complete drawing to industry standard selecting and locating text to support presentation establishing datums and dimensions for drawings drawing sections through an engineering component incorporating correct use of cutting plane symbols and conventions |
Required knowledge |

Evidence Required
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package. | |
Overview of assessment | A person who demonstrates competency in this unit must be able to produce basic engineering drawings to AS 1100.101–1992 Technical drawing – General principles. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts. Specifically the candidate must be able to: work within typical site/teamwork structures and methods apply worksite communication procedures comply with organisational policies and procedures, including quality requirements participate in work meetings comply with quality requirements use industry terminology apply appropriate safety procedures produce drawings in orthogonal and isometric projection to AS 1100.101–1992 Technical drawing – General principles produce drawings in third angle projection, including auxiliary views, sections and assemblies include all details, symbols and notation. |
Context of and specific resources for assessment | This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate. This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with producing basic engineering graphics, or other units requiring the exercise of the skills and knowledge covered by this unit. |
Method of assessment | Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways, including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials. |
