When you have completed this unit of competency you will have developed the knowledge and skills to prepare the CAD environment, produce a basic drawing, modify existing CAD drawings, produce final drawings and perform exit and shut-down procedures. 


Elements of Competency and Performance Criteria

1. Determine drawing requirements


Drawing requirements are checked and interpreted from work order or similar.


Required information is sourced from workshop manuals, customer specifications, product suppliers, designers or similar.


Scope of drawing including layout, additional required information and resources is planned.

2. Produce detail drawings in third angle projection, including auxiliary views, sections and assemblies


Drawing details including assembly and components are completed as per AS 1100 or similar.



Dimensions of various components are determined and inserted where required.



Appropriate symbols for limits and fits, surface texture and geometric tolerances are included.



Simple components or layouts are drawn in third angle projection.



An auxiliary view is drawn of a component, given two views.



Correct convention for parts is shown.

3. Issue and/or file drawing


Drawing is issued and/or filed according to workplace procedures.


Geometric tolerances Simple geometry tolerancing (no datum references, flatness, roundness etc.)Geometry tolerance with datum reference (e.g. parallel squareness)
Simple components or layouts May include fabricated components, machined components, cast and forged components, structural details, electrical electronic components, fluid power components
Parts Mechanical components such as fasteners, bearings, seals, gears, keys, splines etc. Electrical components such as cables, connectors, terminations etc. Fluid power components such as actuators, valves, hoses, connectors, relays etc.
