Unit of competency details

Unit descriptor 

This unit covers interpreting technical drawing applying to any of the full range of engineering disciplines.

Application of the unit 

Technical drawings may utilise perspective, exploded views or hidden view techniques. Drawings are provided to Australian Standard 1100 and/or Australian Standard 1102 and their equivalents from the full range of engineering disciplines.

Standard symbols to Australian Standard 1100 and/or Australian Standard 1102 or equivalent are recognised in field of employment. Technical drawings may include symbol glossaries.

Where any drawing, sketch, chart, diagram is only used as the technique for communication, then this unit does not apply: see Unit MEM12023A (perform engineering measurements) or Unit MEM16006A (Organise and communicate information).

Band : A

Prerequisite units 

Employability skills 

This unit contains employability skills.

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

ELEMENT 

PERFORMANCE CRITERIA 

1. Select correct technical drawing

1.1. Drawing is checked and validated against job requirements or equipment.

1.2. Drawing version is checked and validated.

2. Interpret technical drawing

2.1. Components, assemblies or objects are recognised as required.

2.2. Dimensions are identified as appropriate to field of employment.

2.3. Instructions are identified and followed as required.

2.4. Material requirements are identified as required.

2.5. Symbols are recognised in the drawing as appropriate.

REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

Look for evidence that confirms skills in:

• checking the drawing against job requirements/related equipment in accordance with standard operating procedures
• confirming the drawing version as being current in accordance with standard operating procedures
• where appropriate, obtaining the current version of the drawing in accordance with standard operating procedures
• reading, interpreting information on the drawing, written job instructions, specifications, standard operating procedures, charts, lists and other applicable reference documents
• checking and clarifying task related information
• undertaking numerical operations, geometry and calculations/formulae within the scope of this unit

Required knowledge 

Look for evidence that confirms knowledge of:

• application of AS1100.101 in accordance with standard operating procedures
• relationship between the views contained in the drawing
• objects represented in the drawing
• units of measurement used in the preparation of the drawing
• dimensions of the key features of the objects depicted in the drawing
• understanding of the instructions contained in the drawing
• the actions to be undertaken in response to those instructions
• the materials from which the object(s) are made
• any symbols used in the drawing as described in range statement
• hazard and control measures associated with interpreting technical drawings, including housekeeping
• safe work practices and 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 interpret technical drawings as described.

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 interpreting technical drawings 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 should not require language, literacy and numeracy skills beyond those required in this unit. 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 

RANGE STATEMENT 

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Interpret technical drawing 

AS1100.101 is an extensive work and the candidate is not required to have complete familiarity with all its contents, the application of AS1100 would usually be in line with standard operating procedures; interpretation may require guidance particularly in respect to any geometric tolerancing
