Elements and Performance Criteria

1. Determine drawing requirements
   • Check purpose, scope and information requirements for drawing
   • Interpret available information relevant to project and work requirements, and identify and address further information needs
   • Identify and prepare equipment required to complete work
   • Examine requirements for presentation of drawings
   • Confirm communication requirements during project

Required Skills

Required skills

Required skills include literacy skills sufficient to read and interpret instructions and specifications for drawing work obtaining all relevant job requirements datainformation and specifications necessary to produce the drawing in accordance with workplace procedures planning and sequencing operations checking and clarifying taskrelated information using computer technologies and navigating software numeracy skills sufficient to interpret technical information and conduct mathematical problem solving as required in the scope of this unit applying spatial principles to achieve scale and proportion using drafting equipment appropriate to the drawing method chosen recording completed drawings andor parts lists in accordance with standard operating procedures handling and storing the approved drawings andor parts lists in accordance with standard operating procedures

Required knowledge

Required knowledge includes general knowledge of different approaches to drawing awareness of copyright and intellectual property issues and legislation in relation to drawing environmental and occupational health and safety OHS issues associated with the tools and materials used for drawing quality assurance procedures principles of plane geometry geometric shapes plane geometry geometric construction line types during construction drawing construction four centre method ordinate method sectioning isometric shapes dimensions and notations requirements and purpose of the drawing to be produced requirements and purpose of the engineering parts list sources of relevant datainformation timeframe for completion of drawings persons who can confirm drawing requirements

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 use interpret and apply drawing specifications and produce a complete drawing to AS Technical drawing General principles using manual or CAD tools
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 Specifically the candidate must be able to work within typical siteteamwork structures and methods apply worksite communication procedures comply with organisational policies and procedures including quality requirements participate in work meetings comply with quality requirements use industry terminology apply appropriate safety procedures interpret work and design specifications and use reference material to obtain required information for drawing work produce a detailed engineering drawing to AS Technical drawing General principles and according to work requirements
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 Where applicable reasonable adjustment must be made to work environments and training situations to accommodate ethnicity age gender demographics and disability Access must be provided to appropriate learning andor assessment support when required Where applicable physical resources should include equipment modified for people with disabilities This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with 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 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
