Full title and description

AS 1100.101-1992: Technical drawing — Part 101: General principles. Sets out the basic principles and conventions for technical drawing practice including terminology and abbreviations, drawing-sheet materials and layout, line types and thicknesses, lettering and symbols, drawing scales, methods of projection, sectioning, dimensioning and geometry tolerancing, and the conventional representation of features and parts.

Abstract

This Standard establishes general principles for producing and interpreting technical drawings. It provides rules and recommendations for sheet sizes and layout, line conventions, lettering, scales, projection systems (third-angle by default), sectioning practices, dimensioning, and geometry tolerancing, with appendices covering pictorial development and tolerancing guidance. The Standard was reconfirmed in 2014 and remains current.

Scope

This Standard sets out the basic principles of technical drawing practice for engineering, architectural and related drawings. It covers abbreviations; materials, sizes and layout of drawing sheets; line types and minimum thicknesses; lettering, numerals and symbols; recommended scales; projection methods and view indication (note: drawings in the Standard are shown in third-angle projection unless stated otherwise); sectioning conventions; dimensioning practice including size and geometry tolerancing; and conventions for representing components and repeated features. Appendices include information on pictorial drawing development and geometry tolerancing.

Key topics and requirements

• Terminology, abbreviations and standard notations used on technical drawings.
• Specified drawing-sheet materials, standard sizes and title block/layout conventions.
• Types of lines and minimum thicknesses for different drawing elements (visible, hidden, centre, cutting plane, etc.).
• Lettering and numerals: recommended styles, sizes and spacing for clarity and uniformity.
• Standard drawing scales and guidance on selecting appropriate scales for detail and assembly drawings.
• Projection methods (third-angle projection as default) and rules for arranging views.
• Sectioning conventions: types of section views, hatching standards and indication of cutting planes.
• Dimensioning rules, tolerancing principles and introductory geometry-tolerancing guidance (including recommended practices for size and form control).
• Conventional representations for common components and repetitive features, plus appendices on pictorial projection and tolerancing comparisons.

Typical use and users

This Standard is used by mechanical and civil engineers, architects, draughtspersons, CAD practitioners, manufacturing and fabrication teams, technical educators and quality personnel to ensure consistent creation, interpretation and exchange of technical drawings. It is also used by government and defence procurement bodies, training institutions and standards committees as a reference for drawing practice and for harmonising documentation between organisations.

Related standards

AS 1100.101 forms part of the AS 1100 technical drawing series and is commonly used alongside other parts such as AS 1100.201 (Mechanical technical drawing) and AS 1100.301 (Architectural drawing). Earlier editions (for example AS 1100.101-1984) were superseded by the 1992 edition; the 1992 edition includes Amendment 1 (1994) and was reconfirmed in 2014. Internationally related ISO standards on drawing conventions and tolerancing are relevant for cross-reference.

FAQ

Q: What is this standard?

A: AS 1100.101-1992 is the Australian Standard titled "Technical drawing — Part 101: General principles" that defines general conventions and rules for producing and interpreting technical drawings.

Q: What does it cover?

A: It covers terminology and abbreviations, sheet materials and layout, line types and thicknesses, lettering and symbols, drawing scales, projection methods, sectioning, dimensioning and basic geometry tolerancing, and conventional representations of features and parts. Appendices provide additional pictorial and tolerancing guidance.

Q: Who typically uses it?

A: Engineers, draughtspersons, CAD technicians, manufacturers, architects, educators, quality managers and procurement/defence organisations use it to standardise drawing practice and ensure consistent communication of design intent.

Q: Is it current or superseded?

A: The 1992 edition replaced earlier versions (notably the 1984 edition). It received Amendment 1 in 1994 and was reconfirmed (R2014), and is listed as current/reconfirmed rather than withdrawn. Users should check with Standards Australia or authorised distributors for the very latest status before use.

Q: Is it part of a series?

A: Yes — AS 1100 is a multipart standard for technical drawing; Part 101 provides general principles and is complemented by other parts (for example Part 201 for mechanical drawing and Part 301 for architectural drawing).

Q: What are the key keywords?

A: Technical drawing, drafting, projection, third-angle projection, dimensioning, tolerancing, geometry tolerancing, lettering, drawing sheets, line conventions.
