AS 1100.501—1985 Australian StandardR Technical drawing Part 501: Structural engineering drawing This Australian standard was prepared by Committee MS/32, Technical Drawing. It was approved on behalf of the Council of the Standards Association of Australia on 29 May 1985 and published on 4 November 1985. The following interests are represented on Committee MS/32: Association for Computer Aided Design Limited Association of Consulting Engineers Australia Australian Chamber of Commerce Australian Gas Association Bureau of Steel Manufacturers of Australia CSIRO, Division of Applied Physics Confederation of Australian Industry Department of Conservation, Forests and Lands, Victoria Department of Defence Department of Defence Support Department of Housing and Construction Department of Public Works, New South Wales Electricity Supply Association of Australia Institute of Draftsmen Australia Institution of Engineers Australia Institution of Production Engineers Master Builders Federation of Australia Royal Australian Institute of Architects Society of Automotive Engineers, Australasia Telecom Australia University of Melbourne University of New South Wales University of Queensland The following bodies also participated in the preparation of this standard as members of Subcommittee MS/32/3, Structural Drawing: Australian Institute of Steel Construction Ltd Concrete Institute of Australia Department of Technical and Further Education, New South Wales Forestry Commission of New South Wales National Association of Australian State Road Authorities State Electricity Commission of Victoria Review of Australian Standards. To keep abreast of progress in industry, Australian Standards are subject to periodic review and are kept up to date by the issue of amendments or new editions as necessary. It is important therefore that Standards users ensure that they are in possession of the latest edition, and any amendments thereto. Full details of all Australian Standards and related publications will be found in the Standards Australia Catalogue of Publications; this information is supplemented each month by the magazine ‘The Australian Standard’, which subscribing members receive, and which gives details of new publications, new editions and amendments, and of withdrawn Standards. Suggestions for improvements to Australian Standards, addressed to the head office of Standards Australia, are welcomed. Notification of any inaccuracy or ambiguity found in an Australian Standard should be made without delay in order that the matter may be investigated and appropriate action taken.

It was in 1976 that the above committee decided that rather than have a standard of many parts it would be better if all aspects of technical drawing were consolidated into fewer parts that would embrace the entire discipline. It constitutes Part 501 of a new multi–part standard designated AS 1100. The second deals with matters of general application to all drawings.
