3.2 Correctly identify the requirements in relation to accuracy, tolerances and other critical information.

4 Prepare plots or drawings.

4.1 Correctly access and use CADD functions and features in accordance with operating instructions.

4.2 Correctly access and use peripheral equipment required for the project.

4.3 Prepare and review preliminary drawings in consultation with relevant colleagues.

5 Check drawings and save files.

5.1 Check designs against the project objectives and specifications in accordance with organisational procedures.

5.2 Identify and make required adjustments to designs based on review and consultation with relevant colleagues.

5.3 Store data files in accordance with operating instructions and organisational procedures.

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.

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 industry-current 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 (e.g. people with disabilities, and people who may have literacy or numeracy difficulties e.g. 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 computer-aided drawings.

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.
