Description
This unit of competency covers the skills and knowledge required to use a computer-aided design (CAD) program to produce 3D drawings of jewellery and object models.
Notes
Elements and Performance Criteria
1 Determine project requirements
  • 1.1 Ensure applicable occupational health and safety (OHS), legislative and organisational requirements relevant to CAD applications are verified and complied with
  • 1.2 Review jewellery or object design brief and parameters to determine drawing and documentation requirements
  • 1.3 Examine sketches, drawings and other information and confirm calculations and measurements
  • 1.4 Select and prepare computing equipment and suitable software for jewellery or object designs
2 Use CAD applications to produce 3D model and documentation
  • 2.1 Set up a 3D environment on the screen to allow multiple viewing
  • 2.2 Use editing tools to create features and dimensions of jewellery or object
  • 2.3 Manipulate drawing planes and shapes to create 3D view of jewellery or object
  • 2.4 Produce isometric, perspective and orthographic projections
  • 2.5 Extract mass and area properties of jewellery or object model
  • 2.6 Use principles of perspective to enhance the spatial illusion of jewellery or objects in space
  • 2.7 Apply basic rendering techniques to 3D model of jewellery or object
  • 2.8 Apply drawing protocols to refine and document drawing features
3 Save and back up files
  • 3.1 Determine appropriate presentation for jewellery or object drawings
  • 3.2 Save and file drawings to allow easy access according to workplace documentation system

Overview of assessment
A person who demonstrates competency in this unit must be able to use a CAD program to produce 3D drawings and perspectives of jewellery or object designs.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently:
demonstrate accurate CAD techniques to create and display features of jewellery or object designs
produce 3D CAD models of jewellery or object designs from single, two and three point perspectives
communicate effectively and work safely with others in the work area.
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 applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
Method of assessment
Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering 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 where required.
Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
