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," 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.

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

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.

This guide breaks down the key requirements for drafting, sheet layout, linework, and projection methods. Types of Dimensioning

Types of Dimensioning

• Parallel (Chain): Dimensions placed end-to-end. Risk of cumulative error.
• Running (Baseline): All dimensions originate from a single baseline surface. Preferred for accuracy.
• Diameters and Radii:
  • Circles are dimensioned by diameter (symbol: Ø).
  • Arcs (less than 180°) are dimensioned by radius (Symbol: R).

10. Checklist for Compliance (AS 1100.101–1992)

| Requirement | Check | |-------------|-------| | Correct sheet size & border | ☐ | | Title block complete | ☐ | | Projection symbol present | ☐ | | Line thickness contrast visible | ☐ | | Lettering uniform & legible | ☐ | | All dimensions in mm | ☐ | | No duplicate/missing dimensions | ☐ | | Scale indicated | ☐ | | Section labels used correctly | ☐ | | No mixing of projection systems | ☐ | | Hatching consistent (if sectioned) | ☐ |

3.5 Dimensioning

Dimensions provide the quantitative data required to manufacture the object.

• Terminology: Defines dimension lines, projection lines (extension lines), and leaders.
• Placement: Dimensions should be placed outside the outline of the view where possible and grouped for readability.
• Units: Unless otherwise stated, linear dimensions are in millimetres. Angular dimensions are in degrees.

General Rules

1. Units: Millimetres (mm) are implied. If you use millimetres, do not write "mm" after every number. State in the title block: "Dimensions in millimetres."
2. Decimal Points: Must be prominent. E.g., 12.5 (not 12,5).
3. Legibility: Dimensions must be readable from the bottom or the right-hand side of the sheet.

First Angle Projection (ISO Standard)

• Concept: The object is placed between the observer and the plane.
• Layout:
  • The Front View is at the top or center.
  • The Top View is projected below the Front View.
  • The Left Side View is projected to the right of the Front View.
• Symbol: A truncated cone is shown as a circle (top view) with the side view pointing outward.
