As 1100.101 1992 Technical Drawing General Principles.pdf Upd Instant
AS 1100.101-1992 serves as the foundational Australian standard for technical drawing, establishing a "universal language" for engineering documentation to ensure consistency in line types, lettering, and dimensions. It solidified the use of metric units and ISO A-series paper sizes to reduce manufacturing errors and ensure drawing clarity. You can find more information about this standard through Standards Australia.
AS 1100.101-1992 establishes the fundamental principles for technical drawing in Australia, mandating uniformity through standardized line types, third-angle projection, and dimensioning practices. The standard specifies requirements for sheet layout, including title blocks and metric units (mm), to ensure clear communication across engineering and design disciplines. For detailed technical standards, you can search for the document through Standards Australia. AS 1100.101 1992 Technical drawing General principles.pdf
This guide breaks down the key requirements for drafting, sheet layout, linework, and projection methods. AS 1100
Dimension Elements
- Extension lines – continuous thin, start with a gap from the outline (~1–2 mm).
- Dimension line – continuous thin, terminated with arrowheads (solid, closed, size proportional to line thickness).
- Leader lines – thin line, with arrowhead touching the feature.
4. Dimensioning (Clause 7)
This is where AS 1100.101 gets strict. The PDF dictates that dimension figures must be placed above the dimension line (not broken into it, as in some European standards). Dimension Elements
- Projection lines: Must start with a 2mm gap from the object outline.
- Arrowheads: Defined proportion (length to width ratio of 3:1).
- Symbols: Use Ø for diameter, SR for spherical radius, and square brackets for depth.

3.1 Drawing Sheets and Layout
The standard specifies the requirements for drawing sheet sizes (Designated A-series) to ensure consistent filing and reproduction.
- Sizes: Ranges from A0 (largest) to A4 (smallest). The area of an A0 sheet is 1 $m^2$, with subsequent sizes being half the area of the previous one.
- Borders and Frames: It mandates specific margins and drawing frames to protect the drawing content and allow for binding.
- Title Blocks: A designated area usually located in the bottom right-hand corner. The title block must contain essential information such as the drawing title, drawing number, scale, projection symbol, and the name of the organization.
9. Drawing Types Covered
The standard applies to:
- General assembly drawings
- Detail drawings (single parts)
- Sub-assemblies
- Schematic drawings (basic)
- Orthographic views, section views, and auxiliary views
