Description
This unit of competency covers the skills and knowledge required to identify and interpret original drawings that contain historical information and/or dated presentation protocols, maintain or restore documents and convert information to contemporary formats, including to computer-aided design (CAD) files.
Notes
Elements and Performance Criteria
1 Analyse document components
  • 1.1 Identify the purpose and scope of drawing and application for current work needs
  • 1.2 Examine and interpret drawing protocols applied, symbols, version, origin and completeness of information provided, and identify and address further information needs
  • 1.3 Examine condition of document and determine requirements for presentation, maintenance or restoration
  • 1.4 Identify and prepare equipment required to complete work
2 Maintain or restore document
  • 2.1 Apply treatment or preservation techniques, as required, to restore or maintain document
  • 2.2 Ensure document details are updated and required storage and filing conditions are prepared
3 Transfer data to CAD format, where required
  • 3.1 Determine and verify dimensions and notations
  • 3.2 Select and prepare CAD software and work environment
  • 3.3 Apply standard drawing conventions and techniques according to work requirements
  • 3.4 Produce drawings using CAD that reflect detail provided in original drawing
4 Complete drawing task
  • 4.1 Check and confirm dimensions, angles and proportions
  • 4.2 Ensure drawing is presented according to organisational requirements and contains all relevant and accurate information
  • 4.3 Issue and file drawing according to workplace procedure
  • 4.4 Evaluate work and identify areas for improvement
  • 4.5 Plot or print the final drawing to a standard scale

general notes
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 interpret historical detail drawings and blueprints, restore or maintain, as required, and complete drawing to Australian Standard (AS) 1100.101-1992 Technical drawing - General principles, using CAD tools.
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
interpret work and specifications and use reference material to obtain required information for drawing work
produce a detailed engineering drawing to AS 1100.101-1992 Technical drawing - General principles, and according to work requirements
use CAD software.
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.
