Elements and Performance Criteria

1. Create exploded assembly drawings
   • Drawing preparations, including drawing name, labelling information, dimensions, specifications and information management requirements are obtained/completed
   • Three-dimensional models are prepared for all components
   • Perspective view of the model is created and confirmed
   • Model is exploded so that all components are visible
   • All individual components are labelled in accordance with enterprise requirements
   • Quality checks are completed to ensure accuracy of outcomes
   • Drawings are stored in accordance with enterprise requirements
2. Create job sheets
   • Preparations, including file storage, product coding, inventory information and drawing management requirements are identified and completed
   • Job sheet template is set up in accordance with enterprise requirements and practices
   • Necessary orthographic views are created and dimensioned
   • Sequencing of machine operations and operator requirements are identified and listed
   • Draft job sheets are prepared, reviewed, tested and amended to enterprise requirements
   • Job sheets are stored in accordance with enterprise requirements
3. Convert drawings for CNC applications
   • Conversion requirements are identified and confirmed from the CNC machine specifications
   • Layers and additional information required for final conversion are created
   • Drawing entities are assigned to the relevant layers
   • Conversion to the required file type is completed
   • Converted file is stored in accordance with enterprise requirements

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria Required Skills and Knowledge the Range Statement and the Assessment Guidelines for the relevant Training Package
Critical aspects of evidence	Locate access and interpret all required information Apply safety requirements throughout the work sequence including the use of personal protective clothing and equipment Create a minimum of two exploded assembly drawings including preparation of threedimensional models creation of perspective views exploding the models to expose all components labelling of all components management and storage of drawings Create a minimum of two confirmed job sheets which have the necessary orthographic views and all required management and inventory information Convert a minimum of two drawings for CNC application including the creation of layers assignment of drawing entities and the protection and storage of converted files Work effectively with others
Resource implications	Access to real or appropriately simulated situations involving the application of drawing and drafting techniques and to the related computing operational and inventory support systems This includes real or simulated concepts work areas materials equipment and information on work specifications customer requirements organisation procedures relevant safety procedures and regulations and quality standards
Method of assessment	Assessment methods must confirm consistency or the potential for consistency of performance over time and in a range of workplace relevant contexts Assessment should be by direct observation of work and questioning on underpinning knowledge Assessment may be conducted over time and in conjunction with assessment of other units of competency
Context of assessment	Assessment may occur on the job or in a workplace simulated facility with relevant task requirements work instructions and deadlines

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 in the Performance Criteria is detailed below. Add any 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.
Unit scope	Work involves the identification, selection and use of computer-aided techniques and capabilities, including three-dimensional modelling, exploded assembly drawings and conversion of drawings for CNC applications Activities may include: researching software trends and developments generating and presenting ideas liaising with client and/or other functional areas compiling information
Unit context	OHS requirements include legislation, building codes, material safety management systems, hazardous substances and dangerous goods codes and safe operating procedures Work is carried out in accordance with statutory requirements, organisation insurance requirements, OHS legislation, environmental legislation, manual handling procedures and relevant health regulations Work requires individuals to demonstrate conceptual, analytical and organisational ability, judgement and problem solving skills
Workplace environment	The competency can refer to enterprise and client initiated ideas or requests The competency is applied under broad guidance within routine and non-routine situations
Information and procedures	Customer requirements Work specifications Product catalogues and style manuals or equivalent Inventory systems and records Organisation work procedures and sequencing arrangements Legislation/regulations/national and industry codes and practices relevant to the product Quality and Australian standards and procedures
