Read, interpret and apply engineering drawings


Application

This unit describes the performance outcomes required to read, interpret and determine work task and material requirements from engineering drawings. It involves referring to engineering drawings of systems and components when fabricating, modifying and repairing vehicles or equipment.

It applies to those working on agricultural machinery, heavy commercial vehicles, light vehicles, marine vessels, motorcycles, mobile plant machinery or outdoor power equipment in the automotive service and repair industry.

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


Elements and Performance Criteria

Elements

Elements describe the essential outcomes.

Performance Criteria

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold and italicised text is used, further information is detailed in the range of conditions section.

1. Prepare for work

1.1 Workplace instructions are used to determine job requirements

1.2 Hazards are recognised and precautions are taken according to safety requirements

1.3 Engineering drawings are sourced that relate to the vehicle or equipment being repaired, manufactured or modified

1.4 Engineering drawings are checked to ensure they are current and include latest amendments

2. Read and interpret engineering drawings

2.1 Symbols, codes, legends and diagrams in engineering drawings are identified and interpreted

2.2 Technical information, material specifications, finishes, dimensions and tolerances are identified and interpreted

2.3 Product, system and components represented by the drawing are identified and interpreted

3. Apply information from engineering drawings

3.1 Information from vehicle and equipment engineering drawings is applied to assist in the fabrication, modification and repair of vehicle and equipment systems and components

3.2 Specific customer and work task requirements are identified as required

3.3 Manufacturing processes are identified from drawings, and materials are selected according to customer requirements and workplace procedures

4. Complete work processes

4.1 Work order is prepared according to engineering drawings and workplace procedures

4.2 Engineering drawings are stored and version control maintained according to workplace procedures

Evidence of Performance

Before competency can be determined, individuals must demonstrate they can perform the following according to the standard defined in the unit’s elements and performance criteria and foundation skills:

interpret and apply engineering drawings when fabricating or modifying three different vehicles, vessels or machinery.


Evidence of Knowledge

Individuals must be able to demonstrate knowledge of:

terminology, symbols, codes, legends and diagrammatic representations used in automotive engineering drawings

requirements of quality standards relating to drawings, including relevant Australian Design Rules (ADRs)

procedures for amending and maintaining version control status for engineering drawings, particularly as they apply to vehicle or equipment fabrication, modification and repairs

quality standards applicable to maintaining vehicle or equipment engineering drawings and service information

procedures for reporting work outcomes and maintaining workplace records and information.


Assessment Conditions

Assessors must satisfy NVR/AQTF assessor requirements.

Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.

Assessment must include direct observation of tasks.

Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to having read and interpreted engineering drawings when carrying out fabrication, modification or repairs, e.g. repair orders.

Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.

The following resources must be made available:

automotive repair workplace or simulated workplace

engineering drawings and work task specifications relating to three different vehicles, vessels or machinery

engineering drawing standards, including:

codes

symbols

legends

measurements

ADRs.
