Modification History

Release 1 - New unit of competency

Unit Descriptor

This unit of competency covers the skills and knowledge required to apply functions of computer-aided design (CAD) software programs that are typically used in the production of detail drawings.

Application of the Unit

This unit is suitable for those working within a CAD or drafting work environment and may be applied across engineering and manufacturing environments. It covers competent use of a CAD program to perform basic drawing tasks used in the development of detail drawings. Drawings may include plans, diagrams, charts, circuits, systems or schematics.

This unit includes using computer equipment and selecting software functions in order to generate basic drawing elements.

Work is conducted under supervision.

Licensing/Regulatory Information

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


Not applicable.

Employability Skills Information

This unit contains employability skills.

Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Required Skills and Knowledge

Required skills  

Required skills include:

  • literacy skills sufficient to read instructions for drawings work
  • using computer technologies and navigating software
  • numeracy skills sufficient to interpret technical information and determine scaling and layout issues
  • navigating software to:
  • manipulate drawing entities
  • modify dimension styles
  • create and use layers
  • manipulate the drawing origin
  • define and utilise symbol libraries
  • utilise grids/grid snaps and object snaps
  • display views at multiple scales
  • add title blocks/frame to layout a drawing for printing
  • prepare advanced drawings in plane orthogonal or equivalent
  • set up prototype drawings
  • define and extract attribute data
  • create bills of materials (BOM) utilising attribute data and third-party application software

Required knowledge 

Required knowledge includes:

  • general knowledge of different approaches to drawing
  • awareness of copyright and intellectual property issues and legislation in relation to drawing
  • environmental and occupational health and safety (OHS) issues associated with the tools and materials used for drawing
  • quality assurance procedures
  • CAD program capabilities and processes

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 

A person who demonstrates competency in this unit must be able to use CAD software to produce graphics commonly used in drafting work.

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.

Specifically the candidate must be able to:

  • work within typical site/teamwork structures and methods
  • apply worksite communication procedures
  • comply with organisational policies and procedures, including quality requirements
  • participate in work meetings
  • comply with quality requirements
  • use industry terminology
  • apply appropriate safety procedures
  • identify drawing work requirements and determine appropriate software functions and features
  • identify features and uses of CAD software used in detail and design drafting
  • access and use computing equipment and CAD software functions to produce drawing elements.

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.

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.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with drafting 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.
