Description
This unit of competency defines the skills and knowledge required to produce detailed engineering drawings for mechanical services to Australian Standard (AS) 1100.101 Technical drawing - General principles and is primarily for those performing drafting work for the installation of heating, ventilation, air conditioning and refrigeration (HVAC/R) systems within the mechanical services industry.Critical dimensions and specifications for the drawing are predetermined and drawings are carried out with or without the use of computer-aided design (CAD) systems.No licensing, legislative or certification requirements apply to this unit at the time of publication.
