Unit of competency

Modification History

Release 1. Supersedes and is equivalent to MEM30033A Use computer-aided design (CAD) to create and display 3-D models.

Application

This unit of competency defines the skills and knowledge required to use a computer-aided design (CAD) program to produce and print basic 3D view drawings.

This unit applies to the production of 3D models using CAD software and associated equipment, including 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.

The unit applies to engineering or related activities and is suitable for people giving technical support in manufacturing or engineering operations and those pursuing technical qualifications and careers at paraprofessional or technician level. All work is carried out under supervision.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Pre-requisite Unit

MEM30031 Operate computer-aided design (CAD) system to produce basic drawing elements

Competency Field

Drawing, drafting and design

Elements and Performance Criteria

Elements 

Performance Criteria 

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Confirm drawing requirements

1.1 Follow standard operating procedures (SOPs) and comply with work health and safety (WHS) requirements at all times

1.2 Confirm purpose, scope and information and presentation requirements for drawing

1.3 Identify, interpret and analyse available information relevant to work requirements, and identify and address further information needs

1.4 Identify computing equipment and software used in the organisation

1.5 Identify workflow and procedures for work supervision and confirm communication requirements for the job

1.6 Examine requirements for presentation of drawings

2. Create and display 3D views

2.1 Set up a 3D environment on the screen to allow multiple viewing

2.2 Create 3D views on the screen by manipulation of drawing planes and creation of 3D geometric shapes

2.3 Draw on any plane of the 3D view

2.4 Use editing functions to modify 3D geometric shapes in creating 3D views

2.5 Produce 3D model displays in isometric, perspective and orthographic projections

3. Detail 3D model

3.1 Extract the mass and surface area of a given solid model made from specified material

3.2 Apply basic rendering techniques to render solid model to required criteria

4. Save completed drawing file

4.1 Save file in an appropriate format to enable retrieval and use in a CAD system

4.2 Save file in other formats to enable retrieval in other software applications

Foundation Skills

This section describes those language, literacy, numeracy and employment skills that are essential to performance.

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.

Range of Conditions

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Multiple viewing includes one or more of the following:
  • top views
  • front and side views
  • general 3D view.

3D geometric shapes include one or more of the following:
  • arcs and lines
  • spheres
  • cones
  • cylinders
  • boxes.

Assessment requirements

Modification History

Release 1. Supersedes and is equivalent to MEM30033A Use computer-aided design (CAD) to create and display 3-D models.

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include:

  • identifying modelling work requirements and determining appropriate software functions and features
  • applying CAD functions to produce a rendered 3D model on at least two occasions to Australian Standard (AS) 1100.101 Technical drawing - General principles.

Note: Where a volume and/or frequency is not specified, demonstration must be provided at least once.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

  • solid modelling techniques
  • development of sectioned models
  • multiple viewing
  • 3D geometric shapes
  • use of cutting plane
  • use of cross hatching
  • use of pre-drawn library files and primitives to produce a 3D model
  • how to extract mass and area properties from 3D models
  • application of basic rendering techniques to a 3D model.

Assessment Conditions

  • Assessors must:
  • have vocational competency in using computer-aided design (CAD) to create and display 3D models at least to the level being assessed with relevant industry knowledge and experience
  • satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires.
  • Where possible, assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions that cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
  • Conditions for assessment must include access to all tools, equipment, materials and documentation required including relevant workplace procedures, product and manufacturing specifications.
  • Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
