Unit of competency details

Unit descriptor 

This unit specifies the outcomes required to use computer aided drafting (CAD) applications to produce models and documentation for interior decoration and design projects to meet client and project brief requirements.

Application of the unit 

This unit supports the attainment of skills and knowledge required for competent workplace performance in interior decoration and design operations of all sizes. It applies to the development of 2-D and 3-D drawings that incorporate all standard practice notations and drawing protocols.

This unit requires employability skills in initiative and enterprise, planning and organising and problem solving in order to determine drawing specifications to meet design brief requirements. Communication skills are used to interpret and document design information and complete drawings. Self management and learning skills are applied to gain additional information to support drawing design skills.

EVIDENCE GUIDE 

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 

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

• Effectively design and produce at least two 2-D CAD drawings and two 3-D CAD drawings that document the requirements of the design brief
• Apply drafting and drawing protocols in accordance with Australian Standards and the Building Code of Australia
• Effectively apply design elements and principles to designing with CAD applications
• Comply with legislation, regulations, standards, codes of practice and established safe practices and procedures to design with CAD applications
• Communicate effectively and work safely with others in the work area

Context of and specific resources for assessment 

• The application of competency is to be assessed in the workplace or realistically simulated workplace
• Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints
• Assessment of essential underpinning knowledge, other than confirmatory questions, will usually be conducted in an off-site context
• Assessment is to comply with relevant regulatory or Australian Standards requirements
• The following resources should be made available:

• workplace location or simulated workplace
• materials and equipment relevant to designing with CAD applications
• specifications and work instructions

Method of assessment 

• Assessment must satisfy the endorsed assessment guidelines of the Furnishing Industry Training Package
• Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge
• Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application
• Assessment may be applied under project related conditions (real or simulated) and require evidence of process
• Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances
• Assessment may be in conjunction with assessment of other units of competency
