Elements and Performance Criteria

Determine drawing requirements.
- Review relevant documentation/concept information to determine requirements and processes based on project objectives and parameters.
- Liaise with relevant colleagues to confirm and clarify requirements.
Select and set up CADD package.
Gather object parameters and/or measurements.
- Accurately establish and record critical dimensions and data for the required design.
- Correctly identify the requirements in relation to accuracy, tolerances and other critical information.
Prepare plots or drawings.
Check drawings and save files.

Required Skills

Required skills

literacy skills sufficient to interpret and use digital information including instructions required for the production of computer aided drawings

numeracy skills sufficient for calculations and measurements required for the production of computer aided drawings

Required knowledge

the ways in which CADD is used within a specific industry context

basic principles of CADD

typical features and functions of CADD programs including drawing tools view displays edit functions working with layers plotting and printing

occupational health and safety issues associated with the use of hardware and software

awareness of copyright moral rights and intellectual property issues and legislation associated with the use of CADD

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

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The following evidence is critical to the judgement of competence in this unit

ability to use the standard features and functions of a CADD program to produce drawings

knowledge of CADD capabilities and uses in relation to the specific industry context

Context of and specific resources for assessment

The assessment context must provide for

practical demonstration of skills using an industrycurrent CADD program to develop drawings for a specific workplace purpose

Method of assessment

Assessment may incorporate a range of methods to assess performance and the application of essential underpinning knowledge and might include

evaluation of drawings produced by the candidate

oral or written questioning to assess knowledge of CADD features and functions

review of portfolios of evidence

third party workplace reports of performance by the candidate

Assessment methods should closely reflect workplace demands and the needs of particular groups eg people with disabilities and people who may have literacy or numeracy difficulties eg speakers of languages other than English remote communities and those with interrupted schooling

Assessment of this unit requires access to the materials resources and equipment needed to produce computeraided drawings

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, 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.
Information required for the project may include:	creative objectives measurements/dimensions, e.g. objects, space relevant statutory requirements, e.g. safety scope for making adjustments technical objectives.

Computer-aided designs may be required for a large range of work situations and may include:	costume/fashion designs lighting plots object or product design room/site/stage layouts stage and set design visual art works and/or projects, e.g. community installations, public art, performance.

CADD functions and features to be used must include:	drawing tools (methods for drawing lines, arcs, polylines, texts, dimensions) edit functions plotting and printing view displays working with layers.

CADD functions and feature to be used may include:	3D techniques, e.g. entering coordinates, displaying 3D views how CADD works in an integrated environment isometrics and perspectives macros use of attributes to make project reports.

Peripheral equipment required for the project may include:	plotters printers scanners.
