7. Sectioning
Sections are used to show internal details clearly. AS 1100.101 1992 Technical drawing General principles.pdf
- Cutting Plane: Shown as a Chain Thick line with arrowheads indicating the direction of sight.
- Section Lines (Hatching):
- Thin continuous lines.
- Generally drawn at 45°.
- Used to indicate solid material.
- Spacing should be proportionate to the size of the part (typically 2mm to 10mm apart).
- Adjacent parts: Hatching on adjacent parts in an assembly must be at different angles (e.g., 45° and 135°) or with different spacing.

The Australian Standard AS 1100.101–1992: A Practical Guide
1. Executive Summary
This report provides a comprehensive overview of AS 1100.101-1992, 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.
3. Scales (Clause 6)
The standard defines three main categories of scale: AS 1100
- Full size: 1:1
- Enlargement scales: 50:1, 20:1, 10:1, 5:1, 2:1
- Reduction scales: 1:2, 1:5, 1:10, 1:20, 1:50, 1:100, 1:200, 1:500
You will rarely see a scale like 1:17.5 in a compliant drawing.
How to Obtain AS 1100.101 1992 Technical drawing General principles.pdf
A common search query is finding a free version of this PDF. Please note: This document is copyrighted by SAI Global (formerly Standards Australia). While many educational sites host outdated drafts, the official standard is a paid document.
However, because the standard is withdrawn (replaced by AS 1100.101:2014), you can often find "Superseded" copies via: Cutting Plane: Shown as a Chain Thick line
- University Libraries: Most Australian university portals allow students to download the PDF for free via their library proxy.
- SAI Global Infostore: You can purchase a PDF download (usually around $150 - $200 AUD for the historical copy).
- TAFE NSW/Vic Canvas Modules: Technical teachers often upload the 1992 version as a reading resource.
Warning: Be wary of "free PDF" scam sites. They often contain malware or missing pages (especially page 22, which contains the crucial line diagram).
1. Line Conventions (Clause 4)
This is the most referenced section of the standard. The PDF specifies 15 different basic line types, but the 'Big Four' you must memorize are:
- Thick Continuous Line (0.7mm): Used for visible outlines and edges.
- Thin Continuous Line (0.35mm): Used for dimension lines, extension lines, hatch lines, and leader lines.
- Thin Dashed Line: Used for hidden outlines or edges (what you would see if the object was transparent).
- Thin Chain Line (Long-short-long): Used for center lines, pitch circles, and symmetry axes.
