PERFORMANCE CRITERIA

1. Prepare assembly, layout and detail drafting

1.1. Drawings are prepared in plane orthogonal, isometric projection or equivalent including auxiliary views and sections to Australian Standard 1100.

1.2. Layout, assembly and component drawings are prepared from specification.

1.3. Drawings are dimensioned and labelled using supplied tolerances in accordance with Australian Standard 1100.

1.4. Drawings are produced to specification in accordance with standard operating procedures.

1.5. Standard symbols to Australian Standard 1100 or equivalent are used to specify requirements.

2. Determine component and/or material requirement

2.1. Components and/or materials are selected from supplier/manufacturers' catalogues using design specifications.

Required skills

Look for evidence that confirms skills in:

preparing drawings using appropriate projections and views in accordance with AS1100 or equivalent, see above note in the range statement

producing layout, assembly and component drawings in conformance with specification

inserting all relevant dimensions, tolerances and instructions in the drawing

producing drawings to specification

appropriately using standard symbols in accordance with AS1100 or equivalent in the drawings produced

obtaining component specifications in accordance with work place procedures

reading, interpreting and following information written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents

planning and sequencing operations

checking and clarifying task related information

checking for conformance to specifications

undertaking numerical operations, geometry and calculations/formulae within the scope of this unit

Required knowledge

Look for evidence that confirms knowledge of:

appropriate projection for the drawing purpose

reasons for selecting the chosen projection

reasons for including auxiliary views in drawings

requirements of AS1100 or equivalent with respect to dimensions, tolerances and labels

procedures for producing component, layout and/or assembly drawings

drawing specifications

common symbols used in drawings to AS1100 or equivalent

design specifications of the component

appropriate components and materials from supplier/manufacturers' catalogues

reasons for selecting the chosen components and/or materials

safe work practices and procedures

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 perform basic engineering detail drafting. 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 basic engineering detail drafting 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

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.

Australian Standard 1100

AS1100.100 is an extensive work and its application would usually be in line with standard operating procedures; interpretation would be under guidance particularly in respect to any geometric tolerancing
