This unit of competency covers the skills and knowledge required to produce detailed engineering drawings containing fastening and locking devices. This unit is suitable for those working within a drafting work environment and can be applied across all engineering disciplines. Drawings will usually be carried out with the use of computer-aided design (CAD) systems but may also be done manually. Drawings are produced to Australian Standard (AS) 1100.101-1992 Technical drawing - General principles, from predetermined critical dimensions and specifications. A CD containing templates for exercises can be obtained by contacting blakline@bigpond.net.au for $10 plus postage.
