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 2D drawings using computer aided design system. 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 creating 2D drawings using computer aided design system 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.

Guidance information for assessment

Required skills

Look for evidence that confirms skills in:

obtaining all relevant manuals, instructions and operation procedures for the CAD software and hardware being used

where appropriate, customising the relevant system variables to suit the applicable drafting standards/procedures

where appropriate, customising menus to suit the applicable drafting standards/procedures

where appropriate, customising the system defaults to suit the applicable drafting standards/procedures

where appropriate, developing macros

creating drawings using the appropriate drawing features of the software system

where appropriate, linking drawing entities to database attributes

producing detailed views of the object being drawn

printing drawing files at the appropriate scale

saving drawing files in the appropriate format

producing bills of material from the drawing files/database

extracting supplementary data from the drawing file to meet job requirements

reading, interpreting and following information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents

planning and sequencing operations

checking and clarifying task related information

checking for conformance to specifications

undertaking numerical operations, geometry and calculations/formulae within the scope of this unit

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.

Drawing

Include plans, diagrams, charts, electrical/electronic circuits

Entities

Mean any single item created on the screen and includes for example lines, arcs, circles, text, hatch and dimensions

Attributes

Mean properties associated with an entity and includes for example layer or level, line type, line width, colour and text
