Unit of competency details

Unit descriptor 

This unit covers identifying the drawing requirements, preparing or making changes to engineering drawings, preparing an engineering parts list and issuing the drawings

Application of the unit 

The unit applies to the fields of mechanical, electrical/electronic, fabrication, and fluid power. Specifications may be obtained from design information, customer requirements, sketches and preliminary layouts. Manual drafting and drawing equipment is used, or where a Computer Aided Design (CAD) system is used other units should also be considered. This unit applies to any of the full range of engineering disciplines.

Where a more extensive Computer Aided Drafting System is used for design, then Unit MEM09009C (Create 2D drawings using computer aided design system), should also be considered.

Assessment of performance is to be consistent with the evidence guide.

ELEMENT 

PERFORMANCE CRITERIA 

1. Identify drawing requirements

1.1. Requirements and purpose of drawing are determined from customer and/or work specification and associated documents.

1.3. Drawing requirements are confirmed with relevant personnel and timeframes for completion are established.

2. Prepare or make changes to engineering drawing

2.1. Drafting equipment is selected appropriate to the drawing method chosen.

2.2. Drafting principles are applied to produce a drawing that is consistent with standard operating procedures within the enterprise.

2.3. All work is undertaken safely and to prescribed procedure.

2.4. Completed drawing is approved in accordance with standard operating procedures.

3. Prepare engineering parts list

3.1. Components parts are identified and organised by component type and/or in accordance with organisation/customer requirements.

4. Issue drawing

4.1. Drawings and or parts lists records are completed in accordance with standard operating procedures.

4.2. Approved drawings and or parts lists are copied and issued to relevant personnel in accordance with standard operating procedures.

4.3. Approved drawings and or parts lists are stored and catalogued in accordance with standard operating procedures.

EVIDENCE GUIDE 

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 prepare basic engineering drawings. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

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.

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 preparing basic engineering drawing 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.

Guidance information for assessment
