Elements and Performance Criteria

1. Transfer dimensions from a detail drawing to work or surface
   • Specifications and work requirements are determined and understood using correct and appropriate calculations
   • Marking out is carried out to specifications or standard operating procedures using appropriate tools and equipment
   • Datum points are established
2. Make templates/patterns as required
   • Appropriate template/pattern material is chosen when required
   • Required templates are produced to specifications
   • Correct storage procedures are followed including labelling and identification to standard operating procedures
3. Develop patterns and/or transfer measurements to structures
   • Most appropriate development and/or measurement sequence is chosen and applied
   • Allowances for fabrication and assembly are correctly determined and transferred
   • Measurement transfer/layout of components is checked to ensure accuracy/set out
4. Interpret relevant codes, standards and symbols
   • Relevant standards/codes and symbols are interpreted
   • Requirements of standards/codes are interpreted and applied to materials and processes
5. Estimate quantities of materials from detail drawings
   • Materials are correctly identified
   • Quantities are estimated from drawing
   • Material wastage is minimised

Required Skills

Required skills

Required skills include reading interpreting and following information on written job instructions specifications standard operating procedures charts lists drawings and other applicable reference documents undertaking numerical operations geometry and calculationsformulae within the scope of this unit planning and sequencing operations using techniques and equipment required for marking offout and developing patterns checking for conformance to specifications establishing and marking datum points developing patterns according to specification determining fabrication and assembly allowances and transferring to the pattern where applicable applying the requirements of the codesstandards during the geometric developmentmarking offout process determining material and component quantities from drawings and job specifications minimising material wastage

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 mark offout structural fabrications and shapes 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 apply the skills covered in this unit of competency in new and different workplace situations and contexts Critical aspects of assessment and evidence include examining detailed drawings for fabrication requirements and specifications including materials measurements and tolerances joining methods standards and code requirements correctly determining sequence of measuring andor development correctly establishing and marking datum points accurately transferring measurements to components correctly calculating allowances for fabrication and assembly including shrinkage thickness and insideoutside measurements accurately producing templates
Context of and specific resources for assessment	This unit has been developed to support training in and recognition of trade level competency in marking offout structural fabrications and shapes as applied to a sheet metal or metal fabrication environment Assessment should emphasise a workplace context and procedures found in the candidates workplace 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
Method of assessment	Typically persons engaged in Engineering Tradesperson Fabrication work are required to apply their geometric development skills and techniques across a range of jobs and specifications A single assessment event is not appropriate On the job assessment should be included as part of the assessment process wherever possible Where assessment occurs off the job judgement must consider evidence of the candidates performance in a productive work environment that includes a sufficient range of appropriate tasks and materials to cover the scope of application for this unit 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 supervisors 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	This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with marking offout structural fabrications and shapes or other units requiring the exercise of the skills and knowledge covered by 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
