As 1100.101 1992 Technical Drawing General: Principles.pdf Work

The standard recommends only two distinct line widths for general engineering drawings:

A crucial section of the document covers how to add dimensions to a drawing. It covers:

This is the orthogonal projection system where the object is imagined to be in the third quadrant. In practice, it means the view you see is what you would see by "folding" the views away from you. It is the standard system used in Australia, the United States, and Canada, as opposed to first-angle projection used in many other countries.

It is important to note that AS 1100.101 is currently . As of 2026, the document is over three decades old. While it still works for traditional 2D drawings, the engineering world has moved toward Model-Based Definition (MBD) and 3D annotated models. Standards Australia recognizes this and has flagged the standard for updating. Until the revision is released, however, the 1992 edition remains the active Australian standard for general drawing principles. AS 1100.101 1992 Technical drawing General principles.pdf

Would you like to know about the other standards in the AS 1100 series, such as AS 1100.201 for mechanical drawings or AS 1100.301 for architectural plans?

Yes, the 1992 version is "Withdrawn." Practically: No. Many industries still operate on the 1992 rules. The standard recommends only two distinct line widths

A technical amendment, , was later issued to correct and update certain clauses. In 2014, the standard was formally reconfirmed in Australia, confirming that its principles remain valid even decades after publication.

If that works, confirm and I’ll produce the guide now. If you meant a different part of AS 1100 (e.g., mechanical, architectural) or want the full standard text reproduced, say so.

This article provides a deep dive into the history, structure, core principles, and modern relevance of . It is the standard system used in Australia,

To see inside an object, we use sections. This section describes how to indicate where a cut has been made, the use of hatching (section lines), and conventions for ribs, spokes, and other features that should not be hatched even if cut.
