Application
This unit applies to the undertaking of designated design tasks and the specification in design drawings and graphics of mechanical plant, products, projects, system changes or improvements in domestic, commercial, industrial, agricultural, medical, military or entertainment industries. For ease of reference the term ‘drawing’ is used in this unit.
The design drawing is normally undertaken at the direction of an engineer, scientist or other designer who will pass on a concept brief to the design draftsperson. The concept brief may be a sketch, hard copy plan or document, or a CAD generated file. The unit requires design drawings to be produced using appropriate CAD software. Depending on the task or project, production or supervision of hard copy drawings may also be required.
The unit also includes supervision of detailed drawing production and managing of requests for further information from detailed draftspersons.
This may require completion of appropriate engineering design or evaluation units from the MEM05 Metal and Engineering Training Package depending on the design drawing task and previous industrial experience.
This unit does not cover the production of detailed drawings (often known as shop drawings). Where detailed drawing skills are required the relevant MEM detailed drawing units should be selected.

Required knowledge |
Required knowledge includes: application of the role of engineering design, design drawing and detail drawing in mechanical and maintenance engineering tasks and projects, such as: design specifications mechanical and maintenance procedures technical specifications and descriptions availability and features of standards related to mechanical plant and devices, design, maintenance and alteration AS 1100 Technical drawing, and means of locating and referencing other relevant standards availability and features of standards related to mechanical plant and devices, design, maintenance and alteration application of relevant standard for mechanical designs methods of representing mechanical components and assemblies using sketching and computer graphics, including all relevant symbols, conventions, abbreviations, and so on current and traditional methods of documentation generation and control: computer library files reference charts and catalogue information manual drawing generation of orthogonal images from models worksite procedures for the processing and filing of graphics, specifications and operating and maintenance instructions/manuals WHS and regulatory requirements, codes of practice, risk assessment and registration requirements relevant to mechanical and maintenance applications |
Evidence Required
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 produce a variety of graphical representations of mechanical and maintenance-related assemblies and components that are consistent with design information and relevant standards and conventions. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors must be satisfied that the candidate can competently and consistently: select and apply design criteria to meet requirements of the deign brief review features, functions and context of engineering drawings develop orthographic, isometric and other 3-D graphical representations represent mechanical components and assemblies using sketching and computer graphics represent mechanical components and features using a comprehensive range of standard conventions and graphical techniques represent a range of mechanical assemblies using standard graphical representations recognise when to engage appropriate licensed technical and professional assistance for advice provide documentation, images and files. |
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, then a simulated working environment 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. |
Method of assessment | Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package. Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge. Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application. Assessment may be applied under project-related conditions (real or simulated) and require evidence of process. Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances. Assessment may be in conjunction with assessment of other units of competency where required. |
Guidance information for assessment | Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed. |
