This Indian Standard (Part 44) which is identical with ISO 128-44 : 2001 ?Technical drawings -General principles of presentation - Part 44 : Sections on mechanical engineering drawings issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standardson the recommendation of the Drawings Sectional Committee and approval of the Production and GeneralEngineering Division Council.

ISO 128 was published in 1982 and was accordingly adopted as IS 10714 : 1983. ISO 128 : 1982 waswithdrawn and published again in several parts. In view of this Drawing Sectional Committee decidedto adopt ISO 128-44 : 2001 as IS 10714 (Part 44).

This standard specifies general principles for presenting sections on mechanical engineering drawingsfollowing the orthographic projection methods specified in ISO 5456-2. For areas on sections, representationis according to ISO 128-50, The basic rules for cuts and sections are given in ISO 128-40.
