AS 1100.101-1992, "Technical drawing - General principles," serves as the fundamental Australian standard for technical communication, ensuring consistency in engineering, architectural, and manufacturing drawings. It establishes uniform practices for line types, sheet layout, and projection methods, with licensed copies available through the Standards Australia Store .

If you are looking for further guidance, consider the complementary handbook HB 47-1993 for deeper insight into dimensioning and tolerancing.
The standard uses the ISO 'A' series paper sizes.
One common question is: How does an Australian standard relate to the international ISO system? AS 1100.101—1992 is heavily harmonized with older ISO standards. Specifically, it is to the now-superseded ISO 128:1982 (General principles of presentation) and ISO 129:1985 (Dimensioning). However, because it has been reconfirmed while ISO has moved on to newer revisions (like ISO 128-30:2020), there can be slight variations. Nevertheless, the visual language of an AS 1100 drawing remains largely understandable to any international engineer due to its ISO roots. AS 1100
Sets out requirements for distinct, uniform lettering and numbering. Clear, legible text is essential to prevent misinterpretation of dimensions or notes, and this section provides exact guidelines on character style and size.
The standard emphasizes the use of as the preferred method in Australia, although it also acknowledges First Angle Projection. Proper projection ensures that a 3D object is correctly interpreted in a 2D view. 4. Dimensioning and Tolerancing
AS 1100.101 allows two primary methods of orthographic projection. You must identify which one is being used by a symbol in the title block. If you are looking for further guidance, consider
Provides methods for indicating section views and explains the conventions used in sectioning. Sectioned views are essential for revealing internal features of a part, and this section standardises how those views are drawn and labelled.
The standard was prepared by , whose members included organisations such as the Institution of Engineers, Australia; the Department of Defence; the Institute of Draftsmen, Australia; and universities like the University of New South Wales.
Published by Standards Australia on November 16, 1992, AS 1100.101-1992 is the second edition of a standard that has been decades in the making. It establishes the basic principles of technical drawing practice, covering everything from the specific abbreviations used on a plan to the precise thickness of a hidden detail line.
This report provides a comprehensive overview of , the Australian Standard governing the general principles of technical drawing. This standard is the primary reference for the preparation of technical drawings in Australia, ensuring uniformity and clarity in the communication of engineering and design intent. It supersedes the 1974 version and aligns closely with the corresponding International Organization for Standardization (ISO) standards, facilitating global interoperability.
