This competency is typically performed by advanced operators who develop patterns from drawings and/or specifications. The key factors are the interpretation of dimensions into a physical pattern and ensuring the pattern is suitable for its intended use. It requires the use of a range of well developed skills requiring some discretion and judgement to recognise and resolve a range of problems.
The operator will:
interpreting drawings and specifications
'develop' solid objects into a two dimensional patterns
dimensioning patterns
make allowances for working - joins, bends etc.
This competency cover the stage to develop patterns for the production processes from workplace drawings. This unit applies particularly to the fabrication, thermoforming, composites and rubber lining sectors. It applies primarily to patterns which are essentially two dimensional (although the final product may be three dimensional) and may also be applied where a pattern is used to develop a mould or die or other applications of patterns. It does NOT include patterns such as are used for casting metals, nor plugs for making composite moulds.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
Prerequisites
Prerequisites
This unit has the prerequisite of MEM9.2B Interpret technical drawing.
Employability Skills
The required outcomes described in this unit contain applicable Employability Skills. The Employability Skills Summary of the qualification(s) in which this unit is packaged will assist in identifying Employability Skill requirements.
Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, the range statement and the assessment guidelines for this training package.
Overview of assessment
A holistic approach should be taken to the assessment.
Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.
Where the assessee does not currently possess evidence of competency in MEM9.2B Interpret technical drawing, it may be co-assessed with this unit.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that competence is demonstrated in the knowledge and skills defined in this unit. These may include the ability to:
identify critical materials properties and process characteristics in relation to the process requirements and the end product
develop patterns which are easy to use in the workplace and which produce in-specification products with minimal modification to pattern or product.
identify and take appropriate action on problems and potential problems.
Consistent performance should be demonstrated. For example, look to see that:
the process runs consistently and smoothly.
all safety procedures are always followed.
Assessment method and context
Assessment will be undertaken in a work-like environment using appropriate equipment to demonstrate evidence of how to develop patterns for the production processes from workplace drawings.
Competence in this unit may be assessed:
using industrial patterns and situations
in a situation allowing for the generation of evidence of the ability to recognise, anticipate and respond to problems
by using a suitable simulation and/or a range of case studies/scenarios
through a combination of these techniques.
In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.
Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.
Specific resources for assessment
This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.
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.
Submission Requirements

Assessment Tasks
Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
This describes the essential skills and knowledge and their level required for this unit.
Application of knowledge of the materials, equipment and process sufficient to apply them to the patternmaking process.
A knowledge of the enterprise's procedures, quality requirements, relevant regulatory requirements and the ability to implement them within appropriate time constraints and work standards.
Application of the knowledge of managing risks using the hierarchy of controls applied to developing patterns. Application of approved hazard control and safety procedures and the use of PPE in relation to handling materials, equipment operation and cleanup.
Knowledge as a basis for solving processing and material problems including:
interpreting drawings and extrapolating to physical dimensions
selecting appropriate mediums and materials
hand development of patterns
CAD/CAM assisted pattern development
using other pattern developing tools
using powered hand and bench tools as required
influence of polymer type on pattern requirements
influence of fabrication/manufacture process on pattern requirements.
Competence includes the ability for the practical completion of the job to:
plan own work, including predicting consequences and identifying improvements
identify and describe own role and role of others involved directly in the development of patterns process.
identify factors which may affect product quality or production output and appropriate remedies
identify when assistance is required to solve problems
identify product, materials and work processes appropriate for the individual work role
locate, interpret and apply relevant information and maintain workplace records according to procedures.
Language, literacy and numeracy requirements
This unit requires the ability to read and interpret customer requirements, technical specifications and technical drawings/sketches.
Writing is required to the level of completing workplace forms, quality records and production and reports.
Numeracy is also required, eg to interpret specifications and drawings, and conceptually manipulate two and three dimensional shapes and determine pattern size/shape to give the correct final size/shape.
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Add any 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.
Where reference is made to industry codes of practice and/or Australian/international standards, the latest version must be used.
