Elements and Performance Criteria

1. Confirm drawing requirements
   • Confirm purpose, scope and information and presentation requirements for drawing
   • Identify, interpret and analyse available information relevant to project and work requirements, and identify and address further information needs
   • Identify computing equipment and software used in the organisation
   • Identify work flow and procedures for work supervision and confirm communication requirements through project
   • Examine requirements for presentation of drawings

Required Skills

Required skills

Required skills include reading and interpreting engineering specifications organising information using computer and peripherals using CAD program saving D modes in various file formats preparing drawings in plane orthogonal isometric projection or equivalent

Required knowledge

Required knowledge includes region modelling techniques solid modelling techniques development of sectioned models use of cutting plane use of cross hatching use of predrawn library files and primitives to produce a D model use of third level software to produce D models how to extract mass and area properties how to extract area properties from region models application of basic rendering techniques to a D model

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 CAD to create and display D models
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 identify modelling work requirements and determine appropriate software functions and features apply CAD functions to produce a rendered D model to Australian Standard AS Technical drawing General principles
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 using CAD to create and display D models 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
