Roads and Maritime Services have developed supplements for Australian Standards AS 1742, 1743 & 2890 Supplements to Austroads Guides A comprehensive set of technical guides covering the design, construction, maintenance, operation and safety of Australian and New Zealand road networks in a number of subject areas. CAD System The CAD software used as a basis for this Standard is: AutoCAD 2009 with AutoCAD Architecture (ACA) 2009 To help locate a specific point on a referenced print, most drawings, especially Piping and Instrument Drawings (P&ID) and electrical schematic drawings, have a grid system. In CoDraw, grids are first class graphics objects and as many of them may be used in a design as needed. Technical drawings provide supporting documentation for Ausgrid's Network Standards. Instructions: Find a grid reference on the Google map by simply right-clicking on the map. The content is written at a simpler technical level than many of the standard textbooks on “Engineering Design” so that a wider audience can understand it. Post Code.
