As 1100.101 1992 Technical Drawing General Principles.pdf [exclusive] -
AS 1100.101-1992 provides the foundational "General Principles" for Australian technical drawing, establishing mandatory standards for sheet layout, line work, lettering, and projection methods. By aligning with international ISO standards, this document ensures clarity and consistency across engineering and drafting disciplines.

You can purchase the standard in various formats (hardcopy, PDF for single or multi-user access) from authorized standards distributors such as , Intertek Inform (formerly SAI Global), and Techstreet .
AS 1100.101-1992 establishes the fundamental Australian Standard for technical drawing, providing uniform requirements for sheet layout, line types, lettering, and projection methods to ensure clarity across engineering and design disciplines. Reconfirmed in 2014, this standard aligns Australian practices with ISO international standards and mandates third-angle projection as the default for 2D representations. For a detailed summary of the standard's principles, see the overview at Policy Commons . AS 1100.101 1992 Technical drawing General principles.pdf

The standard defines three main categories of scale: AS 1100
In the world of engineering, manufacturing, and architecture, a clear technical drawing is far more than just a picture—it is a legally binding contract, a manufacturing roadmap, and a universal language. If two engineers in Australia cannot look at the same document and interpret the dimensions, materials, and assembly methods identically, projects cannot be built. This is where the Australian Standard (AS) 1100 series, and particularly , becomes the essential rulebook.

Even though this standard is decades old (originally published in 1992, with previous iterations dating back to the 1980s), it remains the cornerstone of technical drafting education and professional practice across Australia and New Zealand. If you are a first-year engineering student, a CAD draftsman, or a quality assurance manager, understanding this document is not optional—it is essential.
