Use CAD to create and display 3D jewellery and object models

Assessment tool

Version 1.0
Issue Date: May 2024


This unit applies to jewellery and object designers who are using CAD software and equipment to generate and document jewellery and object designs. Documentation may be used to inform production of jewellery or objects and incorporates standard practice notations and drawing protocols.

Band A

Unit Weight 4

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.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Prerequisites

Not applicable.

Employability Skills

This unit contains employability skills.



Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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.

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

application of basic rendering techniques to a 3D model

Required skills include:

communicating ideas and information to enable confirmation of work requirements and specifications

reading and interpreting workplace documents, including working drawings

using mathematical ideas and techniques to correctly complete measurements, calculate area and volume, and estimate other material requirements

attending to detail

planning own work within the given task parameters

using workplace technology, including calculators, measuring and recording devices, and computing equipment

Design features

Design features may include:

materials

dimensions

colours

shapes

Multiple viewing

Multiple viewing includes:

top views

front and side views

general 3D view

Shapes

Shapes may include:

arcs and lines

spheres

cones

cylinders

boxes

Rendering

Rendering is to include, but not be limited to:

the pictorial representation of aspects and perspectives using colours, highlighting and shading to provide depth and photo-like effects

Drawing protocols

Drawing protocols are to include, but not be limited to:

commonly used symbols

lettering standards

standard units of measurement

scale

numbering

legends

abbreviations

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.

Observation Checklist

Tasks to be observed according to workplace/college/TAFE policy and procedures, relevant legislation and Codes of Practice Yes No Comments/feedback
