Description
This unit covers preparing the 3-D computer-aided drafting (CAD) environment, creating and modifying 3-D solid models, and producing output from the 3-D model.
Notes
Elements and Performance Criteria
1 Determine solid modelling requirements
  • 1.1 Check purpose, scope and information requirements for modelling task
  • 1.2 Interpret available information relevant to project and work requirements, and identify and address further information needs
  • 1.3 Identify and prepare equipment required to complete work
  • 1.4 Identify and apply relevant codes, standards and symbols relevant to work
  • 1.5 Consult appropriate personnel to ensure the work is coordinated effectively with others involved in the project
  • 1.6 Obtain and apply workplace occupational health and safety (OHS) and environmental procedures for work
2 Prepare 3-D environment
  • 2.1 Apply workplace procedures to retrieve and manipulate required information and navigate computing technology
  • 2.2 Set up a 3-D environment on the screen to allow multiple viewing
  • 2.3 Create 3-D views on the screen by manipulating drawing planes and inserting 3-D geometric shapes
  • 2.4 Establish coordinate system and orientation according to job requirements
  • 2.5 Determine and exploit key features of solid modelling software package
3 Produce output from 3-D model
  • 3.1 Perform drawing for solid modelling
  • 3.2 Exploit features of modelling software to optimise productivity
  • 3.3 Extract physical properties to job requirement, including volume, mass and centre of gravity
  • 3.4 Apply rendering techniques
  • 3.5 Produce 3-D drawings incorporating section views with all necessary annotation
4 Complete CAD operations
  • 4.1 Confirm model accurately reflects specifications, is presented according to work requirements and contains all relevant information
  • 4.2 Save and file drawing elements according to organisational procedure
  • 4.3 Evaluate work and identify areas for improvement
  • 4.4 Close applications, perform CAD housekeeping and maintain organisational filing system

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 create 3-D models using CAD systems.
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
select and use 3-D CAD software to create solid models that meet design specifications.
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 creating 3-D models using CAD systems 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.
