This unit of competency covers the skills and knowledge required to produce detailed engineering drawings containing bearings and mechanical seals, engineering keys and keyways, holes and shafts to provide specific clearances by applying general tolerances, and confirming the geometric shape of components by applying geometric tolerances. This unit is suitable for those working within a drafting work environment and can be applied across all engineering disciplines. Drawings may be carried out with or without the use of computer-aided design (CAD) systems. A CD containing drawing templates is available for $10 plus postage by contacting BlackLine Design at blakline@bigpond.net.au
