Version 1.0
Issue Date: June 2024
This unit applies to the production of three dimensional models using computer aided design and drawing software and associated equipment. This will include the use of region and solid modelling techniques, section views, and pre-drawn library files. Work also includes extraction of properties and application of basic rendering techniques.
All work is conducted under supervision.

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.
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 | A person who demonstrates competency in this unit must be able to use CAD to create and display 3D models. Competency in this unit cannot be claimed until all prerequisites have been satisfied. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts. |
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 assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate. This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with using CAD to create and display 3D models or other units requiring the exercise of the skills and knowledge covered by this unit. |
Method of assessment | Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials. |

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.
Required skills |
Look for evidence that confirms skills in: reading and interpreting engineering specifications organising information using computer and peripherals using CAD program saving 3D modes in various file formats preparing drawings in plane orthogonal, isometric projection or equivalent |
Required knowledge |
Look for evidence that confirms knowledge of: region modelling techniques. solid modelling techniques development of sectioned models use of cutting plane use of cross hatching use of pre-drawn library files and primitives to produce a 3D model use of third level software to produce 3D models how to extract mass and area properties how to extract area properties from region models application of basic rendering techniques to a 3D model |
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. | |
Multiple viewing | Includes top views, front and side views, and a general three dimensional view |
Three dimensional geometric shapes | May include arcs and lines, spheres, cones, cylinders and boxes |
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 |
---|---|---|---|
Set up a three dimensional environment on the screen to allow multiple viewing. | |||
Three dimensional views are created on the screen by manipulation of drawing planes and insertion of three dimensional geometric shapes. | |||
Any plane of the three dimensional view is drawn on. | |||
Editing functions are used to modify three dimensional geometric shapes in creating three dimensional views. | |||
Wire line, surface and solid face displays are produced in isometric, perspective and orthographic projections. | |||
The mass and surface area of a given solid model made from a nominated material is extracted. | |||
A solid model is rendered to a specified set of criteria. | |||
File is saved in an appropriate format to enable retrieval and use in a CAD system. | |||
File is saved in other formats to enable retrieval in other software applications. |
